keel.Algorithms.Preprocess.Feature_Selection.nonevolutionary_algorithms.RELIEF_F.Relieff

public class Relieff
extends java.lang.Object

Main class of relief-F method using difference between nearest neighbours as evalution measure. Relief Method are based in a selection of relevant features. A feature will be relevant if (ideal case): I is a random instance, H and J the nearest instances to I, and H's class is equal to I's class and different to J's class. Then, a feature X will be relevant if its instance values are equal to I and H ones, and very different to I and J
