Machine Learning Basics 05: Standardization and why you shouldn't do it for linear regression

In this video, I show how to do standardization and why it is not necessary to do standardization in linear regression. At the same time, standardization is critical to machine learning methods such as K nearest neighbor classification and LASSO/Ridge regression.
