Method Detail

map

default <L1,L2> Preprocessor<K,V> map(IgniteFunction<LabeledVector<L1>,LabeledVector<L2>> func)

Map vectorizer answer. This method should be called after creating basic vectorizer. NOTE: function "func" should be on ignite servers.

Type Parameters:

L1 - Type of new label.

Parameters:

func - mapper.

Returns:

mapped vectorizer.
