Method Detail

reset

public void reset()

Description copied from interface: Measure

Resets the cumulated measure value, so the process of computation can be started from beginning (e.g. for a new series of outputs from learning task).

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
