Data Science
 Data Science is a fast growing demand for professionals in business, public agencies and
many organizations.
 Data science is an interdisciplinary field focuses on finding the insights from data.
 These insights may be in structured or unstructured form.
 It unifies the concepts of data analysis, statistics, computer science to understand and
analyze the actual phenomena with data.
 A data scientist develops new methods and algorithms to analyze the data.
Vaibhav Kumar@DIT University, Dehradun
Applications
Data science may be applied in the fields like:
 Customer Analytics: To know the choices, behavior, capacity of customers.
 Fraud Analytics: To find fraudulent customers by credit card issuers and banking
industries.
 Business Analytics: To analyze the investments, revenues, profit, loss of business firms.
 Compliance Analytics: To help organizations transform their audit, risk and compliance
through data analytics.
Vaibhav Kumar@DIT University, Dehradun
Challenges
 Size: There is huge and ubiquitous data available everywhere and it may be available from
multiple sources. Now it is a challenge to decide what amount of data and from which
source should be taken for analysis.
 Features: So many features may be available in data. So it is a challenge to extract only the
useful feature for analysis.
 Parameters: Various parameters are available to analyze the data. So it may be a challenge
to use the appropriate set of parameters for analysis.
 Structure: Finding insights from unstructured data is a challenge.
Vaibhav Kumar@DIT University, Dehradun
Machine Learning
 Machine learning is a subfield of computer science which focuses to develop the
computer algorithm to learn from examples and improve the performance of a task.
 There are three broad categories of machine learning:
 Supervised Learning: Which learns from labeled examples.
 Unsupervised Learning: Which learns from unlabeled examples.
 Reinforcement Learning: Which learns from environment through feedbacks.
 It develops predictive analytics models which allow researchers, data scientists to predict
about future based on past and current data.
Vaibhav Kumar@DIT University, Dehradun
Machine Learning Tools in Data Science
 A list of machine learning algorithms popularly used in data science are given as:
 Regression models
 Artificial Neural Networks
 Decision trees
 Support vector machines
 Naïve Bayes
 K-Nearest Neighbour (KNN)
 K-Means
 Random forest
 Gradient boost model
Vaibhav Kumar@DIT University, Dehradun
Popular Applications
 Ecommerce: Companies are identifying customers based on their purchase and browsing
history to attract them on further purchase.
 Banking and Securities: These industries are monitoring customers to identify illegal
trades and future frauds.
 Media and Entertainment: Using sentiment analysis companies are providing the
products to the customers on their choices.
 Bioinformatics: Expert systems are used in identifying disease and drug discovery.
 Government: Governments are using big data analytics to study the pattern of population
for policy making
 Share Trading: Predicting the share price.
 Many other….
Vaibhav Kumar@DIT University, Dehradun
Future Scope
 Deep learning techniques are trend now a days in the area of data science.
 Accuracy in result and handling with large volume of data implicates the development of
new models
 Researchers are constantly developing new models in this field either by adding new
features to the existing models or by tuning the parameters of analysis.
 There will be a big demand of data scientists everywhere due to the increase rate of data
and required insights from the data.
