keel.Algorithms.Coevolution.CIW_NN.CIW_NN

public class CIW_NN
extends CoevolutionAlgorithm

File: CIW_NN.java The CIW-NN Algorithm. It makes use of three different preprocessing techniques in order to improve the KNN classification. Instance Selection, feature weighting and instance weighting are considered whitin the evolutionary framework
