Constructor Detail

MacroSpecificity

public MacroSpecificity(int numOfLabels)

Constructs a new object with given number of labels and strictness

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 specificity for a label

Specified by:

getValue in interface MacroAverageMeasure

Parameters:

labelIndex - the index of a label (starting from 0)

Returns:

the specificity for the given label
