All Implemented Interfaces:

Serializable, NormalizerStats

public class MinMaxStats
extends Object
implements NormalizerStats

public MinMaxStats(@NonNull
                   INDArray lower,
                   @NonNull
                   INDArray upper)

Parameters:

lower - row vector of lower bounds

upper - row vector of upper bounds

Method Detail

getRange

public INDArray getRange()

Get the feature wise range for the statistics. Note that this is a lazy getter. It is only computed when needed.

Returns:

the feature wise range given the min and max
