    Data Analysts’ Role and trends in 2023 and Beyond

    Data analysts have existed for a long time. In 2022, however, the demand for this position is once again making headlines. In this post, we’ll look at why that is and how to figure out what a Data Analyst is in the year 2020.

    Expanded Responsibilities

    In 2023 and beyond, data analysts are taking on expanded responsibilities beyond traditional data analysis tasks. Here are some areas where their role is evolving:

    Business Strategy and Decision Support:

    Data analysts are becoming strategic partners within organizations. They actively participate in defining business goals and objectives and provide insights that inform strategic decision making. They work closely with business stakeholders to understand their needs, identify key metrics, and develop data-driven solutions to address business challenges.

    Data Engineering and Preparation:

    Data analysts are increasingly involved in data engineering tasks, including data extraction, transformation, and loading (ETL) processes. They collaborate with data engineers to ensure data quality, optimize data pipelines, and develop scalable data architectures. By actively participating in data preparation, data analysts can work with clean, well-structured data that is crucial for accurate analysis.

    Data Visualization and Communication:

    Effective data visualization and communication skills are essential for data analysts. They are responsible for presenting complex analytical findings in a visually appealing and easily understandable manner. By creating interactive dashboards, reports, and presentations, data analysts help stakeholders across the organization interpret and act upon the insights derived from data.

    Machine Learning and Predictive Analytics:

    Data analysts develop machine learning and predictive analytics skills to uncover patterns, trends and relationships in data. Develop and implement predictive models that enable organizations to predict customer behavior, optimize policies, and make data-driven forecasts. Data analysts collaborate with data scientists and engineers to implement machine learning algorithms and integrate them into analytics workflows.

    Data Security and Privacy:

    As organizations handle large amounts of data, data analysts play a vital role in ensuring data security and privacy. Collaborates with IT and security teams to implement information security measures, assess risks and comply with data privacy regulations. Investigators must understand the ethical and legal implications of data processing and ensure adequate safeguards are in place to protect sensitive information.

    Cross-functional collaboration:

    Data analysts collaborate with teams across the organization. Collaborates with business stakeholders, data scientists, IT staff, and management to understand business needs, align analytics efforts with organizational objectives, and drive data-driven projects Effective communication, team operations, and technology for a successful business unit -Ability to bridge the gap between those who are not. technical stakeholders are also important.

    Continuous Learning and Skill Development:

    To keep up with the rapidly evolving data landscape, data analysts must engage in continuous learning and skill development. They stay updated with the latest tools, technologies, and analytical methods. Data analysts actively seek out opportunities for professional development through online courses, workshops, conferences, and networking events. By staying ahead of emerging trends, they can bring innovative solutions to the table and adapt to changing business needs.

    The demand for data analysts is on the rise.

    Companies increasing the number of interviews for Data Analyst roles. One reason for this could be that they’re aiming for a broader range of candidates in the hopes of expanding their data science talent pool.

    Another explanation could be that a Data Analyst is sometimes seen as a “less expensive” counterpart of a Data Scientist. Companies may believe that an analyst may be hired for a lesser wage and trained on the job in data science skills and procedures. Could this be one of the causes for the rise in demand for Data Analysts?

    We don’t believe so. It’s more than likely that the role of Data Analyst has finally become commonplace across industries and businesses of all kinds.


    What is the reason for this? Whereas data was once collected only by individuals for analysis, it is now obtained and collected by both humans and machines. Every day, the machines acquire more and more data, necessitating the hiring of more people to manage and make sense of it all. This work can no longer be done just by data scientists. Furthermore, they are costly.

    What is the role of a data analyst?

    The term “Data Analyst” is perhaps more overused and abused than its relative “Data Scientist.” To begin with, a Data Analyst is often referred to as a Business Analyst or a Business Intelligence Analyst. These may or may not be the same person or function, depending on the firm. A “Data Analyst” is generally someone who analyses data to develop insights for a business, regardless of the official title or the subtle variations between these professions.

    Depending on the industry, type of company, and department in which they work, the Data Analyst’s tasks and position will range slightly. Typically, they supply data that allows businesses to determine things like the products that will be presented to clients.

    This is likely a question you have, whether you’re a candidate seeking for a job as an analyst or a developing company trying to employ big data. With so many Data Analyst job descriptions available and everyone trying to master their big data analytics, determining exactly what a Data Analyst does all day might be difficult.

    The illustration above is a nice place to start. A Data Analyst can be thought of as someone who develops charts like the one shown above to assist business users in answering business questions.

    Data Analyst Core Competencies

    To satisfy the expected need for Data Analysts, bachelor’s degree programmes in data analytics have expanded. MBA degrees, sports management programmes, finance and accounting programmes are all beginning to include data analytics in their curriculum. Data Analyst certification programmes are now accessible from organisations like Cloudera and Dell EMC.

    So, what are the essential talents that someone with a related degree must possess?

    Data analysts must, of course, possess analytical abilities and be conversant with numbers, math, and statistics. Analysts must also be familiar with standard data analysis tools and be able to use them to create queries. SQL and Excel are the two most important tools for any Data Analysts to master.

    Data analysts should be able to use visualization tools like SAS, Cognos, Tableau, and Python and R visualization libraries because their primary role is to develop and present accurate and useful reports.

    Data analysts should be familiar with at least one programming language, such as R, SAS, or Python. SAS and R have always been the programming languages of choice for Data Analysts. However, according to a 2019 survey conducted by analytics staffing firm Burtchworks, Python has finally surpassed SAS and R as the favoured language of Data Analysts.

    In 2023, the following trends will redefine data analytics.

    The market for data analytics is exploding. According to IDC researchers, businesses will spend $215 billion on big data and business analytics solutions in 2021, up 10% from 2020. Data analytics professionals are likewise in high demand. Researchers from the United States Bureau of Labor Statistics predict that the field of data science will grow at a rapid rate (31 percent) through 2030.

    Artificial Intelligence

    For businesses all across the world, artificial intelligence (AI), automation, and machine learning are changing the game. AI is rapidly advancing, particularly in the field of data analytics, where it not only augments human talents but also aids in the extraction of greater economic value. The epidemic and remote work have greatly increased the number of opportunities to track and measure data, resulting in a new data-driven culture in businesses. Investments in AI-based analytics are being fueled by this data culture.

    AI can be used in a variety of ways to increase corporate value. Increasing revenues by forecasting demand and guaranteeing proper warehouse supply, enhancing customer happiness by lowering delivery time, and increasing operational efficiency by automating operations that would otherwise require a human are just a few examples.

    Data Analytics with Composability

    Composable data analytics is a process by which organizations combine and consume analytics capabilities from various data sources across the enterprise for more effective and intelligent decision-making. Such tools can provide greater agility than traditional approaches and feature reusable, swappable modules that can be deployed anywhere, including containers.

     

    With composable analytics, companies can reduce data center costs even if they’ve migrated to the cloud

    Consumer Experience Driven by Data

    Customer experience is critical in any business, whether it’s a product or a service. Because of the current market conditions, customer service is inextricably linked to branding. Data-driven customer experience refers to how businesses collect and use customer data to offer increasingly valuable or delightful client experiences. Consumer interactions with businesses are growing more digital, from AI chatbots to Amazon’s cashier-less convenience stores. This means that practically every component of client interactions may be evaluated, analysed, and converted into insights in order to better understand how procedures might be improved or made more delightful. As a result, there has been a push to personalise the products and services that businesses deliver to their clients. Its demand will continue to rise in the future.

    As A New Industry Standard, Data Fabric

    Data fabric is a novel approach to the age-old problem of combining diverse data sets for analytics. IT can make mission-critical data more discoverable, pervasive, and reusable across all settings of an organisation, including hybrid and multicloud environments, provided it can create a unified data architecture that serves as an integrated layer connecting data endpoints and processes.

    It’s not simply about gaining access to more data sources for analytics. The true value of data fabric architecture is in uniform data management and making it easy for users to access data across several settings.

    Rise of Predictive Analytics

    Predictive analytics is a use of Big Data and Business Intelligence in practise. Various Big Data analytics elements are being successfully used by several organisations to foresee potential future trends. Predictive analytics can be performed on seas of market data, new consumers, cloud apps, social media, or product performance data. According to a recent Facts and Factors analysis, the global predictive analytics industry is expected to reach USD 22.1 billion by 2026.

    Analytics Everywhere

    Consumers will be empowered in the future by tailored and dynamic insights that can help them get the most out of their data or achieve their goals more quickly. Companies who anticipate this trend may have a considerable competitive edge over those that do not provide such capability to their clients. Customers can benefit from personalised services powered by analytics thanks to a combination of AI/ML, automation, and business intelligence.

    Analytics In Edge Computing

    The edge computing industry is expected to increase at a 19 percent compound annual growth rate (CAGR) from $36.5 billion in 2021 to $87.3 billion in 2026. As processing power moves to the edge, supporting technologies (such as data analytics) are likely to move there as well, putting them closer to the physical assets.

    This decision allows for increased speed, agility, and flexibility, as well as real-time analytics and autonomous behaviour for Internet of Things (IoT) devices. According to Gartner researchers, data created, maintained, and analysed in edge environments will account for 50% of data analytics leaders’ responsibilities by 2023.

    FUTURE SCOPE OF DATA ANALYTICS

    In India, extensive usage of Big Data assures high employment, raises income, and allows people to connect with new technologies. By acquiring a significant amount of data, analytics can dramatically alter the current business scenario, expand business models, energise creative processes, and contribute to a company’s overall growth and development.

    Indians Growing Big Data Future

    The Comptroller and Auditor General (CAG), India’s largest reviewer, has established a “Big Data Management Policy” for Indian review and records divisions in an attempt to encourage the use of data analysis to improve their capacities. It entails taking care of the union and state governments’ massive datasets, as well as filing a check with the Indian review and records office.

    Domain Knowledge


    Your effectiveness as a data analyst can be considerably increased by having an understanding of the particular domain you’re working in. You can only ask relevant inquiries, come up with valuable feedback, and provide helpful suggestions if you are aware of the situation and the company’s goals.


    Problem-Solving


    Data analysts should be skilled at resolving problems. This requires the capacity to break down complex problems into simpler pieces, choose the proper data analysis methods, and obtain insights to solve the issue successfully.


    Communication Skills

    Data analysts must be able to explain their conclusions and insights to stakeholders of all technical and non-technical backgrounds. In order to explain the results of complicated data analysis in a way that is both clear and understandable, a person must possess strong written and vocal communication abilities.

     

    Technical abilities

    I’m not going to focus on developing the technical skills required of a data scientist here. To be eligible to apply for data science jobs, you must first complete the following steps.
    Getting to know a programming language

    Exploratory data analysis is something that you should learn about.

    Recognizing the various machine learning algorithms

    Capability to communicate effectively

    Creating a portfolio

     

    Creating a portfolio
    When you feel comfortable with the concepts of data science, it is time to advance. Concentrate on developing a portfolio to learn and showcase your data science work.
    When I say you should work on projects for your portfolio, I mean it. It does not imply undertaking a difficult project. As an example, consider a sophisticated and highly efficient recommendation system. It could be something as simple as your prediction model on the Titanic dataset or a housing price dataset.

    What can you expect from a data analyst job?

    During your training, what skills will you learn? To be honest, it depends on the company you work for, the business area you work in (e.g. sales, business operations, or product creation), and the type of analytics you use. You could, for example, focus on descriptive, prescriptive, or diagnostic analytics. Alternatively, you may study big data systems such as Apache Hadoop.

    Most data analyst internships will not be high-stakes, regardless of what you learn. You’ll still get to learn about important things, but in a secure setting. A good mentor will push you to your limits while without overburdening you. While your specific responsibilities will differ due to the reasons stated above, here are some typical activities to anticipate.

    Collaboration with various team members

    Data analytics courses (or self-study) on the internet can convey the impression that data analysts work alone. In actuality, they must work with a wide range of specialties to communicate and coordinate. Engineers, product designers, and managers are just a few of the types of people you’ll encounter. You’ll also use your talents in a variety of business fields, including sales, marketing, IT, and finance. An internship provides a true taste of data analytics variety. You’ll gain unique insights into how a genuine firm is conducted by supporting management.

    Data cleansing and database maintenance


    Have you completed an online course or practise projects? If that’s the case, you may have conducted data analytics using online datasets. However, these datasets are frequently pre-structured and cleaned. An internship will provide you with real-world data in all of its unstructured, messy beauty! You’ll receive hands-on experience cleaning data using Python and Excel. You could even learn how to employ big data structures to collect and store data. A organised education will teach you important theory, but you will need to apply what you’ve learned in the actual world.

    Performing data analysis


    Of course, the most important aspect of data analytics is conducting analyses. An internship allows you to put all of the statistical techniques you’ve learned into practise. You’ll need some theoretical knowledge of statistics as well as a variety of analytical approaches to get the job. However, once you’re in, this is your opportunity to shine. Finally, you’ll be able to put what you’ve learned in the classroom into practise.

     

    Visualizing data


    The goal of visualisation is to make data more understandable. An intern may be deemed unsuitable for a high-stakes analysis. However, for someone with little experience, making visualisations is a safer endeavour. You’ll probably get to experiment with the company’s internal data tools and apply your own techniques. These data visualisation tools are typically enterprise-level (i.e., paid) and will be unfamiliar to you. Microsoft Power BI, Tableau Desktop (which also has a free version), Salesforce Einstein Analytics, and SAP Analytics Cloud are some of the most popular.

    Entry level Data Analytics projects for beginners

    1. Projects that analyse exploratory data (EDA)

    Without exploratory data analysis, the stage where patterns or discoveries are made in the data, a data analyst’s task is left unfinished. It gives an overview of the general traits of data analysis and how to interpret it using data modelling approaches. Exploratory data analysis is the ideal method to uncover anomalies in numbers, which would have required lengthy, exhausting sessions to complete.

    The following subjects may be helpful when developing an EDA project:

    • Having an understanding of the material and developing an interesting and pertinent hypothesis
    • Using algorithms or data visualisation to solve problems
      Trends in Data Analysis
    • Recognising the connections between variables and interacting with graphs that represent data.

    2.Sentiment Evaluation 

    Understanding the positive or negative polarities of the viewers based on their sentiments can be the goal of a sentiment analysis project for data analysts. These extractions, which are based on opinions posted on websites and social media accounts, can help you understand the general stance your audience takes on a given concept. The numerous categories include joyful, furious, depressed, curious, etc.

    Social media monitoring and online reputation management for any brand

    • Particularly useful for monitoring and comprehending how consumers generally perceive your brand
    • Draw emphasis to important regions.
    • Anything new, like updates on influencer campaigns

    3. Creating chatbots

    Online firms must use chatbots because of their many functionalities. They can help automate customer service procedures and save time and money in the process. Powerful chatbots, which are laced with AI and machine learning algorithms, are everywhere we look, from wearable devices to automated messages in messaging apps.

    A chatbot is a clever computer software that mimics real user interaction through a chat interface. These bots respond to any spoken or written commands in this way and can follow a conversation. Being self-aware, they become smarter the more interactions they have.

    4. A system for recommending movies

    Building a reliable movie recommendation system, one of the simplest ways to provide user-customized services, might not be as simple as it looks. Since the idea is built on an abstract click approach, there would be numerous Machine Learning implementations. You would need significant access to vast data sets of users’ preferences, surfing history, and other information.

    For investment banks, risk modelling

    The act of simulating the movement of a single asset, such as an interest rate, or a portfolio of assets (such as stocks, bonds, futures, options, etc.), in response to various scenarios is known as risk modelling. You may lower the overall risk of your portfolio and boost its performance when risk modelling is done appropriately and consistently across all assets.

    For instance, if a bank wishes to conduct an investment banking transaction, they must take the following into account:

    • What are the expected returns?
    • What dangers exist?
    • What is the likelihood of that?
    • How crucial is this transaction relative to other alternatives?

    Detection of fraud

    While reducing fraud is a typical objective for banks and other financial organisations, analytics may also be used to manage risk rather than only find fraud.

    Analytics can be used to categorise and rank specific consumers who are at risk of fraud before applying various levels of account monitoring and verification. Banks and other financial organizations might prioritize their efforts to detect fraud by looking at the risk of the accounts.

    Data Analytics and Machine Learning:

     Banks leverage data analytics and machine learning algorithms to analyze large volumes of transactional data and detect patterns indicative of fraudulent behavior. By analyzing historical transaction data, customer profiles, and other relevant information, algorithms can identify anomalies, unusual patterns, or suspicious activities that may indicate fraud.

    Transaction Monitoring: 

    Banks use real-time transaction monitoring systems to look for symptoms of fraud in incoming transactions. These systems evaluate transaction parameters such as transaction amount, location, frequency, and divergence from usual behaviour using established rules and algorithms. Unusual or suspicious transactions can set off alarms that require additional examination.

    Behavior Analysis: 

    Banks examine consumer behaviour patterns for aberrations that could suggest fraud. Banks can discover abnormalities or changes in behaviour that may be indicative of fraudulent activity by creating baseline behaviour for individual clients, including transactional patterns, spending habits, and geographical locations.


    Artificial Intelligence (AI) and Natural Language Processing (NLP): 

    Unstructured data sources like as emails, chat logs, and customer support interactions are analysed using AI and NLP technology. These technologies are capable of detecting suspicious language, keywords, or patterns that may indicate fraudulent activity or efforts.


    Network Analysis:

    Network analysis techniques are used by banks to uncover links between various companies involved in fraudulent activity, such as fraud rings or money laundering networks. Banks can find hidden connections and patterns indicative of fraudulent behaviour by mapping relationships and analysing transactional links.


    Enhanced Identity Verification: 

    Banks implement robust identity verification processes to ensure the authenticity of customers and prevent identity theft. This may involve multi-factor authentication, biometric verification, and identity document validation to ensure that individuals are who they claim to be.

    Collaboration and Information Sharing:

     Banks collaborate with other financial institutions, regulatory bodies, and law enforcement agencies to share information on fraud trends, techniques, and known fraudsters. This collaboration helps banks stay informed about emerging threats and improve their fraud detection capabilities.

    Continuous Monitoring and Adaptive Systems:

     Fraud detection systems are continuously updated and refined to keep up with evolving fraud techniques. Banks regularly review and update their fraud detection models, rules, and algorithms to adapt to new fraud patterns and emerging risks.

By employing these techniques, banks can proactively identify and mitigate fraudulent activities, protecting both themselves and their customers from financial harm.

    Credit risk assessment

    Analytics are used by banks and other financial institutions to control the risk of the loans they issue. This is achieved by keeping an eye on the customer-specific data they collect. These details might comprise, but are not restricted to:

    • A customer’s credit rating
    • use of credit cards (how much you owe)
    • the sums outstanding on several credit cards (total debt)
    • Amounts owed on various forms of credit (total credit vs. total debt)

    Analysis of historical data is used to determine a borrower’s creditworthiness or to determine the risk associated with approving a loan. The analysis’ findings aid banks and other financial organisations in assessing both their own and their clients’ risks.

    Creditworthiness Evaluation: Banks assess the creditworthiness of borrowers by analyzing their financial health, repayment capacity, and credit history. This involves reviewing financial statements, income documents, credit reports, and other relevant information to determine the borrower’s ability to repay the loan.

    Credit Scoring Models:

    Credit scoring models are used to quantify and standardize the assessment of credit risk. These models assign numerical scores to borrowers based on various factors such as credit history, income stability, employment status, debt-to-income ratio, and other relevant financial indicators. The scores help banks evaluate the level of risk associated with each borrower.

    Credit Analysis and Underwriting:

    Banks conduct thorough credit analysis and underwriting processes to assess the borrower’s credit risk. This includes evaluating the purpose of the loan, analyzing collateral (if applicable), assessing the borrower’s industry and market conditions, and conducting a comprehensive risk assessment.

    Financial Ratio Analysis:

    Financial ratio analysis is employed to assess the borrower’s financial performance and stability. Ratios such as debt-to-equity ratio, liquidity ratio, profitability indicators, and cash flow metrics are examined to evaluate the borrower’s financial health and ability to service debt obligations.

    Credit History and Payment Behavior:

    Banks review the borrower’s credit history, including their past borrowing and repayment patterns. This involves checking credit reports, credit scores, and delinquency records to assess the borrower’s payment behavior and identify any red flags or potential risks.

    Collateral Assessment:

    In cases where loans are secured by collateral, banks evaluate the quality and value of the collateral. This assessment helps determine the level of security the collateral provides in mitigating credit risk. Factors such as market value, marketability, and the existence of prior liens are considered in collateral valuation.

    Stress Testing and Scenario Analysis:

    Banks perform stress tests and scenario analysis to assess the borrower’s ability to withstand adverse economic conditions. By simulating various scenarios, such as economic downturns or interest rate fluctuations, banks evaluate the impact on the borrower’s repayment capacity and overall credit risk.

    Industry and Market Analysis:

    Banks consider the borrower’s industry and market conditions to assess credit risk. Factors such as industry trends, competition, regulatory environment, and market risks are analyzed to understand the borrower’s business environment and its potential impact on creditworthiness.

    Credit Rating Agencies:

    Banks may also consider external credit ratings provided by reputable credit rating agencies. These ratings provide an independent assessment of the borrower’s creditworthiness and can serve as an additional input in the credit risk assessment process.

    Ongoing Monitoring:

    Credit risk assessment is not a one-time process. Banks continuously monitor borrowers and their credit exposures throughout the loan lifecycle. This includes tracking changes in financial conditions, payment behaviors, and market dynamics to proactively manage credit risk and take appropriate actions when needed.

    Credit risk assessment is crucial for banks and financial institutions to make informed lending decisions, set appropriate terms and conditions, and manage credit exposures effectively. It helps mitigate the risk of default, maintain a healthy loan portfolio, and ensure the overall stability of the institution.

    Comment in Python

    Comments are text blocks that live in your code but are disregarded by the Python interpreter when it runs it. You can use comments to describe the code so that you and other developers can understand what it does and why it’s written the way it is. Simply add a hash mark (#) before your remark text to make a comment in Python: Example : 
    # This is a comment on its own line

    Variable in python

    In Python, variables are names tied to a particular object. They keep a reference to the memory address where an item is stored, often known as a pointer. Once a variable has been assigned to an object, the object can be accessed by using the variable name. You must declare your variables advance. The syntax is as follows: 
    num = 100 #num is of type int
str = "Chaitanya" #str is of type string

    Identifiers - Variable name

    The term “identifier” refers to the name of a variable. When naming variables in Python, there are a few guidelines to follow. 1. The variable’s name must always begin with a letter or an underscore ( ). For example, the variables _str, str, num, and _num are all allowed names. 2. The variable’s name must not begin with a number. 9num, for instance, is not an acceptable variable name. 3. Variable names cannot contain special characters like percent, $, or #; they must only contain alphanumeric characters and underscore (A to Z, a to z, 0-9, or ). 4. In Python, variable names are case sensitive, therefore num and NUM are two separate variables.

    Python Variable Example

    num = 100
str = "VistaAcademy"
print(num)
print(str)

    What is the meaning of a Python keyword?

    A reserved term in Python is one that you can’t use as the name of a variable, class, function, or anything else. These keywords have a specific meaning and are used in the Python programming language for specific purposes.

    Here is a list of the Python keywords. Enter any keyword to get more help.

    False            def           if                          raise
    None             del          import                   return
    True              elif          in                              try
    and              else          is                         while
    as                 except    lambda                 with

    Python data Type

    1. Integer: Integers are whole numbers. They can be positive, negative, or zero. For example: 2, -5, 0.
    2. Float: Floats are numbers with a decimal point. They can be positive, negative, or zero. For example: 3.14, -2.5, 0.0.
    3. String: Strings are sequences of characters. They can be defined using single quotes (‘) or double quotes (“). For example: ‘hello’, “world”, “123”.
    4. Boolean: Booleans represent one of two values: True or False. For example: True, False.
    5. List: Lists are collections of items that are ordered and changeable. They can contain elements of any data type. Lists are defined using square brackets ([]). For example: [1, 2, 3], [‘apple’, ‘banana’, ‘cherry’], [True, False, True].
    6. Tuple: Tuples are similar to lists, but they are immutable (i.e., they cannot be changed). They are defined using parentheses (()). For example: (1, 2, 3), (‘apple’, ‘banana’, ‘cherry’), (True, False, True).
    7. Dictionary: Dictionaries are collections of items that are unordered and changeable. They are organized using key-value pairs. Dictionaries are defined using curly braces ({}). For example: {‘name’: ‘John’, ‘age’: 30}, {1: ‘apple’, 2: ‘banana’, 3: ‘cherry’}, {True: ‘yes’, False: ‘no’}.
    8. Set: Sets are collections of items that are unordered and unchangeable. Sets are defined using curly braces ({}). For example: {1, 2, 3}, {‘apple’, ‘banana’, ‘cherry’}, {True, False}.
    I hope this helps! Let me know if you have any questions.

    Numeric Types

    Integer –

    In Python 3, there is no upper bound on the integer number which means we can have the value as large as our system memory allow 
    x = 20

#display x:
print(x)

#display the data type of x:
print(type(x))

    Float

    It is automatically inferred based on the value we are assigning to a variable. For example here fnum is a float data type. 
    # float number
fnum = 34.45
print(fnum)
print("Data Type of variable fnum is", type(fnum))

    Complex Number

    x = 1j 
    #display x:
print(x)

#display the data type of x:
print(type(x))

    Python Data Type – String

    String is a sequence of characters in Python. The data type of String in Python is called “str”. Strings in Python are either enclosed with single quotes or double quotes. # Python program to print strings and type 
    s = "This is a String"
s2 = 'This is also a String'

# displaying string s and its type

print(s)
print(type(s))
    print(s2) print(type(s2))

    Boolean Values

    In programming you often need to know if an expression is True or False. You can evaluate any expression in Python, and get one of two answers, True or False. Example 1 
    print(10 > 9)

print(10 == 9)

print(10 < 9)
    Example 2
    
a = 200
b = 330

if b > a:
print("b is greater than a")
else:
print("b is not greater than a")

    Operator in Python

    + addition

    x = 5
y = 3

print(x + y)

    -Subtraction

    x = 5
y = 3

print(x - y)

    *Multiplication

    x = 6
y = 3

print(x * y)

    /Division

    x = 12
y = 7

print(x / y)

    %Modulus

    x = 5
y = 2

print(x % y)

    **Exponentiation

    x = 2
y = 5

#shows remender of division

print(x ** y) #same as 2*2*2*2*2

    //Floor division

    x = 15
y = 2

print(x // y)

#the floor division // rounds the result down to the nearest whole number

    Python Assignment Operators

    x +=

    x = 5

x += 3

print(x)
    #answer will be 8

    -=

    x = 5

x -= 3

print(x)
    #answer will be 2

    *=

    x = 5

x *= 3

print(x)
    #answer will be 15 

    /=

    x = 5

x /= 3

print(x)

    %=

    x = 5

x%=3

print(x)
    #shows remainder 2

    //

    x = 5

x//=3
print(x)
    #shows result in integer 2

    **=

    x = 5

x **= 3

print(x)
    #mutiply 5*5*5

    &=

    x = 5

x &= 3

print(x)

    Python Logical Operator

    and

    Logical AND: True if both the operands are true.

    or

    Logical OR: True if either of the operands is true x or y

    # Print a and b is False
    print(a and b)

    # Print a or b is True
    print(a or b)

    # Print not a is False
    print(not a)

     

    Data Structure in Python

    Data structures in Python are ways of organizing and storing data in a structured and efficient manner. They provide different ways to store, access, and manipulate data based on their properties and intended use cases. Python offers several built-in data structures, each with its own advantages and use cases. Some common data structures in Python are:

    Python Data Type – List

    List is similar to tuple in that it is an ordered collection of elements. However, unlike tuple, list is a changeable data type, which means it can be altered. 
    # list of integers
lis1 = [1, 2, 3, 4, 5]
# prints entire list
print(lis1)

    # list of strings
lis2 = ["Apple", "Orange", "Banana"]
# loop through list elements
for x in lis2:
print (x)
    # List of mixed type elements
lis3 = [20, "Chaitanya", 15, "BeginnersBook"]
'''
Print a specific element in list
indexes start with zero
'''
print("Element at index 3 is:",lis3[3])

    Python Data Type – Tuple

    In Python, a tuple is an unchanging data type, which means it cannot be modified. It’s a list of elements that are separated by commas and enclosed in round brackets.

    t1 = (1, 2, 3, 4, 5)
# prints entire tuple
print(t1)

    # tuple of strings

    t2 = ("hi", "hello", "bye")
# loop through tuple elements
for s in t2:
print (s)
    # tuple of mixed type elements
t3 = (2, "Lucy", 45, "Steve")
'''
Print a specific element
indexes start with zero
'''
print(t3[2])

    Python data type Dictionary

    In Python, a dictionary is a collection of keys and values. It is an unordered and changeable data type, and works like an associative array in other programming languages. Here is an example of how you can create a dictionary in Python: 
    my_dict = {'name': 'John', 'age': 30, 'city': 'New York'}
 print(my_dict)
{'name': 'John', 'age': 30, 'city': 'New York'}

 name = my_dict['name']
print(name)
    John You can also add, remove, and modify the elements in a dictionary: 
    my_dict['age'] = 25
print(my_dict)
{'name': 'John', 'age': 25, 'city': 'New York'}
    < 
    
 my_dict[‘phone’] = ‘555-555-5555’
print(my_dict)
    {'name': 'John', 'age': 25, 'city': 'New York', 'phone': '555-555-5555'}
    output 
    del my_dict['phone']
print(my_dict)
{'name': 'John', 'age': 25, 'city': 'New York'}

    Sets:

    • Sets are unordered collections of unique items.
    • They do not allow duplicate values.
    • Useful for checking membership and performing set operations (union, intersection, etc.).
    • Defined using curly braces: my_set = {1, 2, 3}
    Sets are useful when you want to store a collection of items without any duplicates and quickly check for membership or perform set operations like union, intersection, and difference. Sets are defined using curly braces {} or the set() constructor. Here’s an example of using sets in Python:
    Creating a Set:
    You can create a set using curly braces {} or the set() constructor. Sets automatically remove duplicate elements, so only unique elements are stored.   
    # Creating a set using curly braces
my_set = {1, 2, 3, 4, 4, 5}
print(my_set)  # Output: {1, 2, 3, 4, 5}

# Creating a set using the set() constructor
another_set = set([3, 4, 5, 6, 6])
print(another_set)  # Output: {3, 4, 5, 6}
    Adding Elements to a Set:
    my_set = {1, 2, 3, 4, 5}
my_set.add(6)
print(my_set)  # Output: {1, 2, 3, 4, 5, 6}

    Removing Elements from a Set:

    You can remove an element from a set using the remove() method. If the element doesn’t exist in the set, it will raise a KeyError
    my_set = {1, 2, 3, 4, 5}
my_set.remove(4)
print(my_set)  # Output: {1, 2, 3, 5}

    Checking Membership in a Set:

    my_set = {1, 2, 3, 4, 5}
print(3 in my_set)  # Output: True
print(6 in my_set)  # Output: False

    Set Operations: 

    set_a = {1, 2, 3, 4, 5}
set_b = {4, 5, 6, 7, 8}

# Union of two sets
union = set_a | set_b
print(union)  # Output: {1, 2, 3, 4, 5, 6, 7, 8}

# Intersection of two sets
intersection = set_a & set_b
print(intersection)  # Output: {4, 5}

# Difference between two sets
difference = set_a - set_b
print(difference)  # Output: {1, 2, 3}

# Symmetric difference (elements in either set, but not both)
symmetric_diff = set_a ^ set_b
print(symmetric_diff)  # Output: {1, 2, 3, 6, 7, 8}

    if statement in python

    In Python, an if statement is used to execute a block of code only if a certain condition is true. Here is the general form of an if statement in Python: if condition: # code to be executed Here is an example of an if statement in Python: 
    x = 10
if x > 5:
print("x is greater than 5")
    In this example, the condition is x > 5. If the condition is true (in this case, it is), then the code inside the if block will be executed. In this case, the code inside the if block is print(“x is greater than 5”), which will print the string “x is greater than 5” to the console. You can also include an else clause in an if statement to specify a block of code that should be executed if the condition is false: 
    x = 3
if x > 5:
print("x is greater than 5")
else:
print("x is not greater than 5")
    n this example, the condition is x > 5, which is false. Therefore, the code inside the else block will be executed, which will print the string “x is not greater than 5” to the console. You can also use the elif keyword to specify additional conditions that should be checked if the initial if condition is false. For example 
    x = 3
if x > 5:
print("x is greater than 5")
elif x == 5:
print("x is equal to 5")
else:
print("x is less than 5")
    In this example, the initial condition is x > 5, which is false. The second condition, x == 5, is also false. Therefore, the code inside the else block will be executed, which will print the string "x is less than 5" to the console.

    Loops in python

    Loops are used to execute a block of code repeatedly for a certain number of times or until a certain condition is met. There are two types of loops in Python: for loops and while loops. Here is an example of a for loop that iterates over a range of numbers and prints each one to the console: 
    for i in range(10):
print(i)
    This will output the numbers 0 through 9. Here is an example of a while loop that continues to execute as long as a certain condition is true: 
    x = 0
while x < 10:
print(x)
x += 1
    This will output the numbers 0 through 9, just like the for loop above. Both for loops and while loops can be controlled using the break and continue statements. The break statement will exit the loop completely, while the continue statement will skip the rest of the current iteration and move on to the next one. I hope this helps! Let me know if you have any questions.

    While Loop in python

    A while loop in Python allows you to repeat a block of code as long as a certain condition is True. Here is the general syntax: while condition: code block The code block will be executed repeatedly as long as the condition is True. When the condition becomes False, the loop will terminate and control will be passed to the next line of code after the loop. Here is an example of a simple while loop that counts down from 5 and prints the count at each iteration: 
    count = 5
while count > 0:
print(count)
count -= 1
    This will output the following: 5 4 3 2 1 It is important to include a way to modify the condition within the loop, or else the loop will run forever (this is known as an infinite loop). In the example above, the count variable is decremented by 1 each time the loop runs, so eventually count will become 0 and the condition will be False, terminating the loop. You can also use the break statement to terminate a while loop early, before the condition becomes False. 
    count = 5
while True:
print(count)
count -= 1
if count == 0:
break
      This loop will run the same as the previous example, but it uses an infinite loop and the break statement to achieve the same result.

    function in python

    Step 1: Defining a Function

    In Python, a function is a block of code that performs a specific task and can be reused throughout your program. To define a function, you use the def keyword followed by the function name and a pair of parentheses. Here’s an example:     
     >def greet(name):
print(f"Hello, {name}!")
    In this example, we’ve defined a function called greet that takes one parameter name.

    Step 2: Function Parameters

    Parameters are the inputs that a function receives. You can pass values (arguments) to a function when you call it. In the above example, name is a parameter.

    Step 3: Function Body

    The indented block of code under the def statement is the function body. This is where you write the code that performs the desired task. In our greet function, the body contains a single line that prints a greeting.

    Step 4: Calling a Function

    To use a function, you call it by using its name followed by parentheses. You can pass values (arguments) to the function if it expects any. Here’s how you call the greet function:
    greet("Alice")
    This will output: Hello, Alice!

    Step 5: Return Statement (Optional)

    Functions can also return values back to the caller using the return statement. Here’s an example:
    def add(a, b):
    return a + b
    In this example, the add function takes two parameters (a and b) and returns their sum.

    Step 6: Function Call and Return Value

    When you call a function that uses the return statement, you can capture the returned value in a variable:
    result = add(5, 3)
print(result)  # This will print 8

    Step 7: Default Parameters (Optional)

    You can provide default values for function parameters. These values will be used if the caller doesn’t provide a value for that parameter:
    def power(base, exponent=2):
    return base ** exponent

    example of function in python

    CALCULATOR WITH IF FUNCTION

    def add(x, y):
    return x + y

def subtract(x, y):
    return x – y

def multiply(x, y):
    return x * y

def divide(x, y):
    if y != 0:
        return x / y
    else:
        return “Cannot divide by zero”

print(“Select operation:”)
print(“1. Add”)
print(“2. Subtract”)
print(“3. Multiply”)
print(“4. Divide”)

choice = input(“Enter choice (1/2/3/4): “)

num1 = float(input(“Enter first number: “))
num2 = float(input(“Enter second number: “))

if choice == ‘1’:
    print(“Result:”, add(num1, num2))
elif choice == ‘2’:
    print(“Result:”, subtract(num1, num2))
elif choice == ‘3’:
    print(“Result:”, multiply(num1, num2))
elif choice == ‘4’:
    print(“Result:”, divide(num1, num2))
else:
    print(“Invalid Input”)

    To-Do List Program:

    tasks = []
def add_task(task):
tasks.append(task)
print("Task added:", task)

def remove_task(task):
if task in tasks:
tasks.remove(task)
print("Task removed:", task)
else:
print("Task not found")

def display_tasks():
print("Tasks:")
for index, task in enumerate(tasks, start=1):
print(f"{index}. {task}")

while True:
print("Select operation:")
print("1. Add Task")
print("2. Remove Task")
print("3. Display Tasks")
print("4. Quit")

choice = input("Enter choice (1/2/3/4): ")

if choice == '1':
task = input("Enter task: ")
add_task(task)
elif choice == '2':
task = input("Enter task to remove: ")
remove_task(task)
elif choice == '3':
display_tasks()
elif choice == '4':
break
else:
print("Invalid Input")
    Function with Default Argument:
    def power(x, exponent=2):
    return x ** exponent

result = power(5)  # Uses default exponent (2)
print(result)
result = power(3, 4)  # Custom exponent (4)
print(result)

    Top 10 reason for Power BI is the finest tool for data analytics

    What is Power BI?

    Power BI is a data-sharing platform that is hosted in the cloud. You can share your experiences with your colleagues once you’ve created reports with Power Query, Power Pivot, and Power View. This is where Power BI comes into play. You may upload Excel workbooks to the cloud and share them with a select set of coworkers using Power BI, which is actually a feature of SharePoint online. Not only that, but your colleagues can use filters and slicers to emphasise data in your reports. They’re finished by Power BI, a straightforward way to share your Microsoft cloud-based analysis and insights.

    You may use Power BI features to:

     

    Collaborate with your colleagues on presentations and questions.

    Update your Excel file using data from on-site sources.

    Power BI for Data Analysis

    Visualizations that are interactive and that are simple to integrate with Microsoft software


    Power BI adds tremendous value by providing a consolidated view of your company’s performance through stunning visualisations and interactive dashboards. Power Business Intelligence Services Desktop offers a free canvas for drag-and-drop navigation, a large library of interactive visualisations, and easy report creation and publishing in the Power BI service for the analyst at heart. You can also make unique, more complex visualisations with Power BI. Because Microsoft Power BI is part of the Microsoft business product suite, it has tight connectivity with other prominent Microsoft business products and tools including Microsoft Excel, Azure, and SQL Server.

    On powerbi.microsoft.com, you have access to a large library of educational materials.

    Microsoft offers a familiar and easy user interface that takes little time to get used to. Users get access to an extensive information base. New users can access tutorials, videos, presentations, and blogs to help them maximise the tool’s potential and solve problems quickly. Not to mention the Microsoft community, which has over a million members who share their experiences and seek solutions to their questions.

    Graphics analysis does not necessitate programming knowledge.

    Power BI can help analysts who perform graphics analyses on a regular basis. Simple data analysis, fast and dynamic calculations, and a wide range of visualisation options will help you save time when conducting ad-hoc analyses.

    Additional data sources


    Power BI can connect to more than 60 prominent solutions used by businesses today. Spark, Hadoop, and SAP are just a few examples. Data can be integrated directly with the Power BI engine, so users don’t have to model data in their source systems. The system also works with the most popular operating systems, including Windows, iOS, and Android.

    Power BI has excellent data modelling capabilities.

    Data modeling is one of the functions that is used to connect multiple data sources in a BI tool using relationships. The relationship defines how data sources are connected to each other and based on these data valuable visualizations can be created.

    With the data modeling function, you can create custom calculations on existing tables. The results of these calculations can be directly presented in Power BI visualizations.

    Reports and data analysis are securely shared.

    Users can publish their reports and visualisations immediately on the Internet and send them in e-mails using the Microsoft Power BI service. It can be accessed by anyone who is interested. Report access can be restricted to a single person, or a single report can be made available to everyone in the company, but the data displayed can be restricted to a specific group of people. For example, Boston-based sellers have access to solely Boston-based sales data, whereas the company’s CEO gets access to sales across the United States.

    Power BI integration is unrestricted. Embedding and the ability to embed in a third-party programme are both available.

    Microsoft Power BI’s inventors claim that their solution can be integrated into any software ecosystem. 
    Numerous links with major third-party software and Microsoft technologies demonstrate this. 

    As mentioned earlier, Microsoft is constantly working to extend the connectivity of this system, enabling users to import even more databases and data sources.

    Power BI Pro's data analysis gives you immediate access to reports and dashboards.

    You can share desktops and reports with the right people from anywhere in the world using Power BI. The system is also versatile because it works with popular operating systems like as Windows, iOS, and Android. Any updates or changes to the data will trigger alerts, allowing you to quickly analyse the most important KPIs and take strategic action.

    Unlimited access to local data (on-premises) and data in the cloud

    Power BI stores all local information and data in the cloud in one centralized location that can be accessed anytime, anywhere. You can also use pre-built links to improve data import from solutions such as Marketo, Salesforce, Google Analytics and many more. Additionally you are able to connect to different types of on-premises data storages such as SQL Server, Oracle or Hadoop. It also have pre build connectors to such cloud storages as Google BigQuery or all storages from Azure offering.

    different PowerBI views

    Report View: This is the default view that displays data visualisation in reports. You may use a variety of templates and visualisations to build several report pages.

    Data View: The converted data is shown in a table format with columns and rows. It also lets you construct new calculated columns for even more information.

    Model View, also known as Relationship View, aids in the creation of data model relationships. This view displays all of the models built in the data, allowing you to compare or build diagrams depending on subsets of the model.

    Power BI comes in a variety of formats.

    Power BI Desktop may be downloaded and installed on your personal computer, allowing you to connect to a data source, convert your data, analyse it, and visualise it using templates.

    Power BI services include: It is a SaaS (software as a service) cloud-based service (software as a service). You can also link to data here, although modelling options are limited.

    Power BI mobile app: The PowerBI app, which is available for iOs, Android, and even Windows, allows users to securely access dashboards and reports from any device.

Dashboards provide a holistic view of the data, enabling stakeholders to monitor metrics, track progress, and make informed decisions in real-time.

    Experimental design and A/B testing

    Experiment: Cooking Up Curiosity

    Imagine you’re in a kitchen, trying to create the perfect recipe for a delicious cake. Experimental design is just like that! Scientists and savvy businesses cook up experiments to answer questions. They mix different ingredients (or variables) and see how they affect the outcome. It’s all about turning curiosity into solid answers.


    The A and the B: Let the Battle Begin

    Ever had to choose between two different ice cream flavors? That’s the spirit of A/B testing! Let’s say you’re designing a website. You wonder if a blue “Sign Up” button gets more clicks than a green one. A/B testing sets up a battle: A is the blue button, and B is the green button. By comparing how people interact with both, you find out which one wins the popularity contest.


    The Wizardry of Randomness: Creating Fair Tests

    Imagine you’re a magician hosting a magical contest. You want to make sure everyone has an equal chance to win, right? That’s where randomness comes in! In experiments and A/B testing, we use random assignment. It’s like shuffling cards before a game. This ensures that each group (A and B) is a fair representation of the whole crowd.


    Crunching the Numbers: Analyzing Results

    Ever played a game and tallied up the scores to see who won? That’s exactly what happens after an experiment or A/B test. Data is collected, numbers are crunched, and voila! The winner emerges. Statisticians, who are like math detectives, help make sense of the data. They use their magic to decide if the results are reliable or just coincidental.


    Hunting for Insights: Unearthing Discoveries

    Imagine you’re a treasure hunter on a quest for a hidden chest of gold. In the world of experiments, data is the treasure, and insights are the gold. A/B testing helps you find out which changes work better and why. Maybe people prefer big fonts on a website or shorter videos for better attention. Insights like these guide decisions and make things awesome!

    You’ll plan studies and run A/B tests to evaluate the effectiveness of various treatments or adjustments. Making data-driven judgments and evaluating the efficacy of tactics are both aided by this.

    Experimental design and A/B testing are important methodologies used in data science to assess the impact of changes or interventions and make data-driven decisions. Here’s an overview of these concepts:

    1. Experimental Design:

    Experimental design refers to the process of planning and organizing experiments to obtain reliable and meaningful results. It involves defining research questions, identifying variables, designing treatments or interventions, and specifying the control groups. Experimental design aims to minimize bias, confounding factors, and sources of variability to ensure the validity and reliability of the experiment.

    2. Treatment and Control Groups:

    In experimental design, participants or subjects are divided into different groups. The treatment group receives the intervention or change being tested, while the control group does not receive the intervention and serves as a baseline for comparison. Random assignment is typically used to allocate participants to groups, ensuring that any observed differences between the groups are not due to pre-existing factors.

    3. A/B Testing:

    A/B testing, also known as split testing, is a specific form of experimental design used in marketing, user experience (UX), and web development. It involves comparing two versions of a webpage, advertisement, or user interface (A and B) to determine which performs better in terms of a specific metric, such as conversion rate, click-through rate, or user engagement. A random sample of users is assigned to each version, and their interactions and behavior are analyzed to determine the impact of the changes.

    4 Hypothesis Testing:

    In both experimental design and A/B testing, hypothesis testing is employed to determine if the observed differences between groups are statistically significant or simply due to chance. Data scientists formulate null and alternative hypotheses and use statistical tests, such as t-tests, chi-square tests, or ANOVA, to analyze the data and make inferences about the population based on the sample data.

    5.Sample Size Determination:

    Determining the appropriate sample size is crucial for the validity and power of an experiment. Data scientists use statistical power analysis to calculate the required sample size, taking into account the desired level of significance, effect size, and statistical power. A larger sample size generally leads to more precise and reliable results.

    6.Data Collection and Analysis:

    During the experiment, data scientists collect relevant data to evaluate the impact of the intervention. This may include quantitative metrics, user feedback, survey responses, or other forms of data. The collected data is then analyzed using statistical methods to assess the differences between groups and draw conclusions.

    7. Drawbacks and Considerations:

    Experimental design and A/B testing have certain limitations and considerations. These include potential biases, such as selection bias or sampling bias, that may affect the generalizability of the results. Data scientists need to carefully design experiments, control for confounding factors, and ensure that the observed effects are meaningful and not spurious.

    Experimental design and A/B testing provide rigorous methodologies for testing hypotheses, optimizing interventions, and making data-driven decisions. They help organizations understand the impact of changes, evaluate different strategies, and continuously improve their products, services, or user experiences.

    What is deep Learning in Data science explain with example?

    As Data turns into the main thrust of the advanced world, essentially everybody has coincidentally found such terms as data science, AI, deep learning, and data mining.

    Deep learning is a class of AI algorithms that utilizes numerous layers to continuously extract high-level features from the raw input.

    Deep learning is a subset of Machine Learning, which then again is a subset of Artificial Intelligence. Man-made consciousness is an overall term that alludes to methods that empower PCs to emulate human conduct. AI addresses a bunch of calculations prepared on information that make the entirety of this conceivable.

    Deep learning is a subset of AI that prepares a PC to perform the human-like task, like such as picture distinguishing proof forecast making and speech recognition.

    What is AI

    Artificial Intelligence(AI) is a wide-going part of software engineering, worried about building brilliant machines fit for performing assignments that normally require human intelligent.

    Artificial Intelligence is the replication of human intelligence in computers.

    Artificial intelligence (AI) is subsequently, founded on the possibility of the capacity of a machine or PC program to think(reason), comprehend and learn like people.
    From the definition of intelligence, we can also say that artificial Intelligence is the study of the possibility of creating machines able to apply knowledge received from data in manipulating the environment.

    Example of AI

    If you look particular type of content on youtube or Netflix such as comedy movies it shows you option of a list of comedy movies to choose in the future as per your taste.

    What is machine learning

    Man-made reasoning is extremely immense. Machine learning(ML) is a subset of Artificial Intelligence. That is the place where ML comes in.
    Machine learning(ML) is a bunch of statistical instruments to gain from information.
    The core of ML is in showing PCs how to take in and make forecasts from information without essentially being customized.

    Machine learning is a technique for information investigation that robotizes analytical model structure. It is a part of artificial intelligence dependent on the possibility that frameworks can gain from data, identify patterns and make decisions with minimal human intervention.

    what is deep learning ?

    Deep Learning, on the other hand, is just a subset  of Machine Learning, inspired by the structure of a human brain. Deep learning algorithms attempt to draw similar conclusions as humans would by continually analyzing data with a given logical structure. To achieve this, deep learning uses a multi-layered structure of algorithms called neural networks.

    What is a neural network?

    Neural networks are a series of algorithms that mimic the operations of a human brain to recognize relationships between vast amounts of data. They are used in a variety of applications in financial services, from forecasting and marketing research to fraud detection and risk assessment.

    A neural  network has many layers. Each layer performs a specific function, and the complex the network is, the more the layers are.
    That is the reason a neural network  is additionally called a multi-facet perceptron.
    The most flawless type of a neural organization has three layers:

    • The input layer
    • The hidden layer
    • The output layer

    As the names recommend, every one of these layers has a particular reason. These layers are comprised of hubs.

    1. The input layer picks up the input signals and transfers them to the next layer.
    2. It gathers the data from the outside world.
    3. The hidden layer performs all the back-end tasks of calculation.
    4. A network can even have zero hidden layers

    you will have to train a neural network with some training data as well, before you provide it with a particular problem.

    Why Deep Learning is well known now days?

    Why Deep Learning is well known now days?

    The Deep learning market was worth USD 2.28 Billion in 2017 and is relied upon to arrive at USD 18.16 Billion by 2023, at a CAGR of 41.7% from 2018 to 2023. The base year considered for this review is 2017, and the figure time frame is from 2018 to 2023.

    Deep Learning is acquiring a lot of prominence because of it’s matchless quality as far as exactness when prepared with gigantic amount  of data. The product business now-a-days moving towards machine learning. AI has become vital in each area as a method of making machines Intelligent.

    The most important difference between deep learning and traditional machine learning is its performance as the scale of data increases. When the data is small, deep learning algorithms don’t perform that well. This is because deep learning algorithms need a large amount of data to understand it perfectly.

    Some time before Deep learning was utilized, conventional AI techniques were basically utilized.

    Deep learning functions as follows:

    1. It first distinguishes what are the edges that are generally applicable to discover object.
    2. It then, at that point, expands on this progressively to track down what blend of shapes and edges we can find. For instance, regardless of whether specif quality are available,on object.
    3. After consecutive hierarchical identification of complex concepts, it then decides which of these features are responsible for finding the answer.

    Feature Extraction aims to reduce the number of features in a dataset by creating new features from the existing ones (and then discarding the original features). These new reduced set of features should then be able to summarize most of the information contained in the original set of features.

    Because this type of learning acts as a powerful brain, a large amount of data for training is required. So much data is needed that before big data and cloud computing, the amounts of data and processing power were not easily available. But just because there needs to be a lot of data, it does not mean the data must be structured. Deep learning can process both unlabeled and unstructured data. This learning method also creates more complex statistical models. With each new piece of data, the model becomes more complex, but it also becomes more accurate.

    Deep learning in data science

    Since this kind of learning goes about as an incredible cerebrum, a lot of data for preparing is required.

    So much data is needed that before big data and cloud computing, the amounts of data and processing power were not easily available.
    But just because there needs to be a lot of data, it does not mean the data must be structured.
    .

    Deep learning can deal with both unlabeled and unstructured data.
    This learning technique additionally makes more statistical measurable models. With each new piece of information, the model turns out to be more complicated, yet it additionally turns out to be more precise.

    How deep learning utilizes a hierarchical level of artificial

    Deep learning, on the other hand, is a subset of machine learning that does machine learning using a hierarchical level of artificial neural networks. Artificial neural networks are constructed in the same way as the human brain, with neuron nodes connected in a web-like pattern. While typical programmes develop analysis using data in a systematic way, deep learning systems’ hierarchical function allows machines to process data in a non-linear manner.

    Examples of Deep Learning

    Translations
    People are migrating across countries and companies are giving their products and services to people all over the world, making the world smaller than it has ever been. While this is excellent news, the most significant stumbling factor is language. Wouldn’t it be simpler if everyone spoke the same language? Deep learning algorithms, thankfully, can assist in this aspect by automatically detecting and translating from one language to another. Deep learning can assist a visitor in need of directions or even government officials meeting to discuss vital economic reforms.

    Customized Experiences

    As a last example, suggestions offered by sites like Amazon and Netflix are another deep learning function we witness on a daily basis. They offer recommendations based on our history, and this strategy has helped many of us discover items, films, and TV shows we didn’t even know existed. The recommendations function will only improve as technology advances in the coming years.

    Recognition of Facial Expressions

    In fact, facial recognition has a wide range of applications, therefore deep learning is very useful in this area. Some businesses, for example, are implementing facial recognition stations for their personnel. Other services, such as Facebook, are employing deep learning to recognise faces in photos in this way. Customers may be able to finalise orders and pay for things using facial recognition in the future.

    Defense and Aerospace

    Did you know that deep learning can help with national security issues? Satellites that need to detect areas of interest are one application. Deep learning could potentially be useful in the military. Rather than taking excessive risks, officers will be able to identify not only safe zones but also danger zones using deep learning.

    Medical Investigations

    Deep learning is being used in the medical business, and it’s now being used to detect cancer cells, as we discussed earlier. Cancer researchers at UCLA were able to employ deep learning in a high-tech microscope. The microscope can reliably distinguish cancer cells from other cells by using high-dimensional data.

    Virtual Personal Assistants

    Next, you presumably have Cortana, Alexa, or Siri in your home (most do these days), and they all use deep learning. Deep learning is necessary by companies like Google and Apple to interpret our speech. If you’ve ever wondered how Siri understands what to say in response to our queries, deep learning is the answer.
