Undoubtedly, Data Science is one of the most revolutionary technologies of our era.
It involves deriving useful insights from data to solve complex real-world
problems. This session is a full course on Data Science that covers everything you
need to know to master the field.

Before we get started, let's take a look at the agenda. The first module is an
introduction to Data Science, which covers all the basic fundamentals. Next, we
have the Statistics and Probability module, where you'll understand the math behind
Data Science and Machine Learning algorithms. Then, we have the Basics of Machine
Learning module, where you'll learn about different types of Machine Learning
algorithms.

After that, we move on to the Supervised Learning Algorithms module, which covers
Linear Regression, Logistic Regression, Decision Trees, Random Forest, K-Nearest
Neighbor, and Naive Bias. Each of these modules explores how these algorithms can
be used to solve complex problems with the help of real-world examples.

Introduction to Data Science
Data science is currently one of the most in-demand technologies due to the
increasing amount of data being generated and the need to process and make sense of
it. In this session, we will discuss data science in depth, including its various
sources, the data life cycle, machine learning, and more.
