Webb17 maj 2024 · Loss function = OLS + alpha * summation (squared coefficient values) In the above loss function, alpha is the parameter we need to select. A low alpha value can lead to over-fitting, whereas a high alpha value can lead to under-fitting. In scikit-learn, a ridge regression model is constructed by using the Ridge class.
