Interface DatasetMapping<L1,L2>

Type Parameters:

L1 - Type of labels before mapping.

L2 - Type of labels after mapping.

public interface DatasetMapping<L1,L2>

This class represents dataset mapping. This is just a tuple of two mappings: one for features and one for labels.

Method Summary

Modifier and Type	Method and Description
default Vector	mapFeatures(Vector v) Method used to map feature vectors.
L2	mapLabels(L1 lbl) Method used to map labels.
static <L> DatasetMapping<L,L>	mappingFeatures(IgniteFunction<Vector,Vector> mapper) Dataset mapping which maps features, leaving labels unaffected.
