Well, I need a classifier in that can support partial_fit() and can give a
probability for prediction proba_predict() (in case of multi-class, not
only binary). PassiveAggressiveClassifier and Perceptron have no
proba_predict() method, and SGDClassifier have a proba_predict() method but
supported only for binary classification.
