Constructor Detail

MultilabelWindowClassificationPerformanceEvaluator

public MultilabelWindowClassificationPerformanceEvaluator()

Method Detail

reset

public void reset()

Description copied from interface: ClassificationPerformanceEvaluator

Resets this evaluator. It must be similar to starting a new evaluator from scratch.

Specified by:

reset in interface ClassificationPerformanceEvaluator

Overrides:

reset in class WindowClassificationPerformanceEvaluator

reset

public void reset(int L)

Overrides:

reset in class WindowClassificationPerformanceEvaluator

addResult

public void addResult(weka.core.Instance x,
             double[] y)

Add a Result. NOTE: In theory, the size of y[] could change, although we do not take into account this possibility *yet*. (for this, we would have to use y[] differently, another format for y[] e.g. HashMap, or store more info in x)

Specified by:

addResult in interface ClassificationPerformanceEvaluator

Overrides:

addResult in class WindowClassificationPerformanceEvaluator

Parameters:

x - the instance to be classified

y - an array containing the estimated membership probabilities of the test instance in each class

getPerformanceMeasurements

public Measurement[] getPerformanceMeasurements()

Description copied from interface: ClassificationPerformanceEvaluator

Gets the current measurements monitored by this evaluator.

Specified by:

getPerformanceMeasurements in interface ClassificationPerformanceEvaluator

Overrides:

getPerformanceMeasurements in class WindowClassificationPerformanceEvaluator

Returns:

an array of measurements monitored by this evaluator

getDescription

public void getDescription(StringBuilder sb,
                  int indent)

Description copied from interface: MOAObject

Returns a string representation of this object. Used in AbstractMOAObject.toString to give a string representation of the object.

Specified by:

getDescription in interface MOAObject

Overrides:

getDescription in class WindowClassificationPerformanceEvaluator

Parameters:

sb - the stringbuilder to add the description

indent - the number of characters to indent
