Ridge Regression and Lasso Regression

# Introduction

In the regression prediction, in addition to the linear regression and the polynomial regression mentioned before, there are many other regression methods as well. For example, Ridge Regression, LASSO Regression and various other regression methods derived from the next week's classification method. In this section, we first introduce the ridge regression and the LASSO regression methods, both of which belong to regularization methods, which can solve several problems that linear regression cannot cover.
