Class MIEMDD

java.lang.Object

weka.classifiers.Classifier

weka.classifiers.RandomizableClassifier

weka.classifiers.mi.MIEMDD

All Implemented Interfaces:

Serializable, Cloneable, CapabilitiesHandler, MultiInstanceCapabilitiesHandler, OptionHandler, Randomizable, RevisionHandler, TechnicalInformationHandler

public class MIEMDD
extends RandomizableClassifier
implements OptionHandler, MultiInstanceCapabilitiesHandler, TechnicalInformationHandler

EMDD model builds heavily upon Dietterich's Diverse Density (DD) algorithm.
It is a general framework for MI learning of converting the MI problem to a single-instance setting using EM. In this implementation, we use most-likely cause DD model and only use 3 random selected postive bags as initial starting points of EM.
