Method Detail

canEvaluate

public abstract String canEvaluate(weka.classifiers.Classifier classifier)

Tests whether the classifier can be evaluated.

Returns:

null if successful, otherwise error message

init

public abstract ResultItem init(weka.classifiers.Classifier classifier)
                         throws Exception

Initializes the result item.

Parameters:

classifier - the current classifier

Returns:

the initialized history item

Throws:

Exception - if initialization fails

doEvaluate

protected abstract void doEvaluate(weka.classifiers.Classifier classifier,
                                   ResultItem item)
                            throws Exception

Evaluates the classifier and updates the result item.

Parameters:

classifier - the current classifier

item - the item to update

Throws:

Exception - if evaluation fails

evaluate

public void evaluate(weka.classifiers.Classifier classifier,
