org.datavec.api.transform.analysis.histogram.NDArrayHistogramCounter

All Implemented Interfaces:

Serializable, HistogramCounter

public class NDArrayHistogramCounter
extends Object

A counter for building histograms on a NDArray columns. This is a bit of a hack, using DoubleHistogramCounter internally. This should (one day) be optimized to use native ND4J operations
