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.
