Package ai.libs.jaicore.ml.evaluation.evaluators.weka

Class MonteCarloCrossValidationEvaluator

java.lang.Object

ai.libs.jaicore.ml.evaluation.evaluators.weka.MonteCarloCrossValidationEvaluator

All Implemented Interfaces:

ai.libs.jaicore.basic.events.IEventEmitter, ai.libs.jaicore.basic.ILoggingCustomizable, ai.libs.jaicore.basic.IObjectEvaluator<weka.classifiers.Classifier,java.lang.Double>, IClassifierEvaluator

public class MonteCarloCrossValidationEvaluator
extends java.lang.Object
implements IClassifierEvaluator, ai.libs.jaicore.basic.ILoggingCustomizable, ai.libs.jaicore.basic.events.IEventEmitter

A classifier evaluator that can perform a (monte-carlo)cross-validation on the given dataset. Thereby, it uses the AbstractSplitBasedClassifierEvaluator to evaluate the classifier on a random split of the dataset.
