java.lang.Object

org.nd4j.linalg.dataset.api.preprocessor.NormalizerMinMaxScaler

All Implemented Interfaces:

DataSetPreProcessor

public class NormalizerMinMaxScaler
extends Object
implements DataSetPreProcessor

Created by susaneraly on 5/25/16. A preprocessor that applies min max scaling Can take a range X -> (X - min/(max-min)) * (given_max - given_min) + given_min default given_min,given_max is 0,1
