WebMay 16, 2024 · The red line is going to be the test score on different alphas. We will also need a cross-validation object, there is no one good answer here, this is an option: cv = KFold(n_splits=5, shuffle=True, random_state=my_random_state) To illustrate my point on the importance of multiple-step parameter search, let’s say we want to check these alphas: WebOct 7, 2015 · There is a small difference in between Ridge and RidgeCV which is cross-validation. Normal Ridge doesn't perform cross validation but whereas the RidgeCV will perform Leave-One-Out cross-validation even if you give cv = None (Node is taken by default). Maybe this is why they produce a different set of results.
