Classification¶. The Ridge regressor has a classifier variant: RidgeClassifier.This classifier first converts binary targets to {-1, 1} and then treats the problem as a regression task, optimizing the same objective as above. The predicted class corresponds to the sign of the regressor’s prediction.

Examples are ridge regression or SVM. You can also optimize the objective function without any loss function, e.g. simple OLS or logit. $\endgroup$ heroes 3 pl download free
