Class MultiLabelClassifier

java.lang.Object

it.uniroma2.sag.kelp.predictionfunction.classifier.multiclass.MultiLabelClassifier

All Implemented Interfaces:

Classifier, PredictionFunction

public class MultiLabelClassifier
extends Object
implements Classifier

It is a multi label classifier. It is suitable for multi label classification tasks where every example can be associated to zero, one or multiple classs. Basically, given a multi label classification task with C classes, starting from the output provided by C different binary classifiers (on which this classifier relies on) operating in a 1-vs-All Schema , the final predicted classes are the ones associated to positive scores
