keel.Algorithms.Lazy_Learning.KStar.KStar

public class KStar
extends LazyAlgorithm

File: KStar.java The KStar Algorithm. A new instance based classifier, wich rather than using distance, defines a "transformation probability" from test instance to each train instance. It accumulates all the "transformation probabilities" and select the class wich has the most
