          edu.udo.cs.yale.operator.preprocessing.normalization.Normalization

All Implemented Interfaces:

ConfigurationListener

public class Normalization
extends PreprocessingOperator

This operator performs a normalization. This can be done between a user defined minimum and maximum value or by a z-transformation, i.e. on mean 0 and variance 1.
