Constructor Detail

MacroRecall

public MacroRecall(int numOfLabels)
Constructs a new object with given number of labels

Parameters:
numOfLabels - the number of labels
Method Detail

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

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(int labelIndex)
Returns the recall for a label

Specified by:
getValue in interface MacroAverageMeasure
Parameters:
labelIndex - the index of a label (starting from 0)
Returns:
the recall for the given label
