WebNov 18, 2024 · Regression is very commonly used in machine learning for time series modeling, forecasting, and understanding cause-effect relationships between different variables. Different types of regression used in machine learning are linear regression, logistic regression, ridge regression, polynomial regression, and lasso regression. WebRegularization works by adding a penalty or complexity term to the complex model. Let's consider the simple linear regression equation: y= β0+β1x1+β2x2+β3x3+⋯+βnxn +b. In the above equation, Y represents the value to be predicted. X1, X2, …Xn are the features for Y. β0,β1,…..βn are the weights or magnitude attached to the features ...
