Publisher: Ermin Dedic## Description

Math for Data Science is the 3rd course in a series. To obtain the best results, consider taking the first two courses in the series first (1. Data Science Masterclass for Beginners and 2. Python for Data Science: From the Basics to Advanced). This course begins with an introduction to linear algebra by answering questions such as, "What makes *linear* equations *linear*?". The priority is for students to understand linear equations and systems of linear equations, including the different forms of a linear equation and systems of equations in various forms. Then, the focus is on approaches to solving matrix equations. Next, you will discover an essential mathematical object, the vector space.

In the two remaining topics for linear algebra, you will explore properties of vector spaces (i.e., a basis for a vector space, linear combinations and span, linear independence, and the dimension of vector and subspaces) and see how to apply the previous knowledge via least-squares approximation. The next module begins by introducing you to probability. You will first understand the concept of a probability model and its axioms before exploring simple counting. You will then learn to think about and solve simple discrete probability problems, including conditional Bayes problems.

Afterward, you will study a few new concepts, random variables, probability mass function, expectation, and joint probability mass functions. You will then advance to working with continuous variables and working out probabilities for more than one variable at a time. Finally, you will comprehend how to apply statistical inference to obtain insights. Data Science is one of the sexiest fields of the 21st century. Since the start of the century, organizations have been keeping larger volumes of data, updating it more frequently, and using a wider variety of it (not just numbers but texts, tweets, audio, video, image, and more). The world needs you to take the massive amount of raw facts and work with them to produce actionable insights. Be insightful by enrolling today!
