Modifier and Type	Method and Description
void	configure(VocabCache<T> vocabCache, WeightLookupTable<T> lookupTable, VectorsConfiguration configuration)
void	finish()
java.lang.String	getCodeName()
boolean	isEarlyTerminationHit() Since GloVe is learning representations using elements CoOccurences, all training is done in GloVe class internally, so only first thread will execute learning process, and the rest of parent threads will just exit learning process
double	learnSequence(Sequence<T> sequence, java.util.concurrent.atomic.AtomicLong nextRandom, double learningRate) Learns sequence using GloVe algorithm
void	pretrain(SequenceIterator<T> iterator) pretrain is used to build CoOccurrence matrix for GloVe algorithm

pretrain

public void pretrain(@NonNull
                     SequenceIterator<T> iterator)

pretrain is used to build CoOccurrence matrix for GloVe algorithm

Specified by:

pretrain in interface ElementsLearningAlgorithm<T extends SequenceElement>

Parameters:

iterator -

learnSequence

public double learnSequence(@NonNull
                            Sequence<T> sequence,
                            @NonNull
                            java.util.concurrent.atomic.AtomicLong nextRandom,
                            double learningRate)

Learns sequence using GloVe algorithm

Specified by:

learnSequence in interface ElementsLearningAlgorithm<T extends SequenceElement>

Parameters:

sequence -

nextRandom -

learningRate -

Returns:

average score for this sequence

isEarlyTerminationHit

public boolean isEarlyTerminationHit()

Since GloVe is learning representations using elements CoOccurences, all training is done in GloVe class internally, so only first thread will execute learning process, and the rest of parent threads will just exit learning process

Specified by:

isEarlyTerminationHit in interface ElementsLearningAlgorithm<T extends SequenceElement>

Returns:

True, if training should stop, False otherwise.
