Linear Algebra

Linear algebra is the branch of mathematics that handles vectors and matrices. Operations involving vectors and matrices are fundamental to many areas of the physical sciences, as well as data science and machine learning techniques. Understanding linear algebra is important to know how and why data science tools work.

Here, linear algebra concepts will be introduced and later used to explain the data science methods used. It is possible to use methods from data science without understanding the exact way they work. However, a more complete understanding of linear algebra is possible.

Note

The terms vector and matrix may not be familiar, but they will be introduced in detail along with the operations that are performed with them.
