WebJun 22, 2024 · Ridge regression is a small extension of the OLS cost function where it adds a penalty to the model as the complexity of the model increases. The more predictors(mⱼ) you have in your data set the higher the R² value, and the higher the chance your model will overfit to your data. Ridge regression is often referred to as L2 norm regularization.
