Class StandardScaler

java.lang.Object

org.nd4j.linalg.dataset.api.iterator.StandardScaler

Deprecated.

Use NormalizerStandardize for equivalent functionality. NormalizerStandardize is more stable (for examples, when a column contains all the same values for every example) but otherwise provides equivalent functionality. See also NormalizerMinMaxScaler

@Deprecated
public class StandardScaler
extends Object

Standard scaler calculates a moving column wise variance and mean http://www.johndcook.com/blog/standard_deviation/
