public interface BinaryScoreClassifier
extends Classifier

Many algorithms linear a binary separation between two classes A and B by representing the target labels with a -1 ad 1. At prediction, the output is a real valued number - where the sign indicates the class label. This interface indicates that an algorithm conforms such behavior, and that the "0" class corresponds to the -1 label, and the "1" class corresponds to the 1 label.
