Method Detail

getName

public String getName()

Description copied from interface: Measure

Gets the name of a 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).

Returns:

the average measure value computed so far
