Package se.hb.jcp.cp.measures

Class ObservedProbabilityLogLoss

java.lang.Object

se.hb.jcp.cp.measures.ObservedProbabilityLogLoss

All Implemented Interfaces:

IMeasure, IObservedMeasure, IObservedProbabilisticMeasure

public class ObservedProbabilityLogLoss
extends java.lang.Object
implements IObservedProbabilisticMeasure

The observed log loss measure depends on the prediction made and the true label. See [V. Vovk, I. Petej, "Venn-Abers Predictors", On-line Compression Modelling Project (New Series) Working Paper #7, 2012] for the definitions used here.
