LabelBasedPrecision

public LabelBasedPrecision(int numOfLabels)

Constructs a new object with given number of labels

Parameters:

numOfLabels - the number of labels

Method Detail

getIdealValue

public double getIdealValue()

Description copied from interface: Measure

Gets an 'ideal' value of a measure. The 'ideal' means, that the value represents the best achievable performance of a learner for an prediction of a multi-label task and associated true labels.

Returns:

the ideal value
