TīmeklisOverall, the models obtained here by ridge and lasso we not particularly useful since the best value of \(\lambda\) (as found by cross-validation) was always the smallest value in the grid we pass to the function, this suggests that the best overall value is zero, meaning the both Ridge and Lasso regressions wil perform as well as ordinary ... Tīmeklis2024. gada 17. maijs · 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.
