Constructor Detail

Performance

public Performance(Point<Object> values,
                   AbstractEvaluationWrapper evaluation,
                   int evalType,
                   int classLabel,
                   weka.classifiers.Classifier classifier)
            throws Exception

Initializes the performance container. If the Evaluation object is null, then the worst possible values for the measures are assumed (in order to assure a low ranking).

Parameters:

values - the values

evaluation - the evaluation to extract the performance measures from, can be null

evalType - the type of evaluation

classLabel - the class label index (if applicable)

classifier - the classifier

Throws:

Exception - if retrieving of measures fails
