Constructor Detail

MacroAUC

public MacroAUC(int numOfLabels)

Creates a new instance of this class

Parameters:

numOfLabels - the number of labels

Method Detail

getName

public String getName()

Description copied from interface: Measure

Gets the name of a measure.

Specified by:

getName in interface Measure

Returns:

the name of a measure.

getValue

public double getValue()

Description copied from interface: Measure

Gets the value of a measure. The measure is incrementally cumulated for learner's prediction by each Measure.update(MultiLabelOutput, boolean[]) call. The value returned by the method, returns sum of all update calls divided by the number of calls (average of all measures for all predictions).

Specified by:

getValue in interface Measure

Returns:

the average measure value computed so far

getValue

public double getValue(int labelIndex)

Returns the AUC for a particular label

Specified by:

getValue in interface MacroAverageMeasure

Parameters:

labelIndex - the index of the label

Returns:

the AUC for that label
