- Wu method. According to the algorithm 2 for computation of the class probabilities described in [Wu04]. The library returns the index of the class with the largest probability.
- Vote-based method. If the binary classifier predicts the feature vector to be ini-th class, the number of votes for the classiis increased by one, otherwise the vote is given to thej-th class. If two classes have equal numbers of votes, the class with the smallest index is selected.
