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.
