Class BasicLabelAwareIterator

java.lang.Object

org.deeplearning4j.text.documentiterator.BasicLabelAwareIterator

All Implemented Interfaces:

java.util.Iterator<LabelledDocument>, LabelAwareIterator

public class BasicLabelAwareIterator
extends java.lang.Object
implements LabelAwareIterator

This is simple class, for building Sentence-Label pairs for ParagraphVectors/Doc2Vec. Idea is simple - you provide SentenceIterator or DocumentIterator, and it builds nice structure for future model reuse
