Overview of different fusion models.

Model	Dim	Submodels	Model	Dim	Submodels
FPW	300	TF-IDF, LDA, Word2vec	TDE	600	TF-IDF, LDA, Word2vec
FPW	300	TF-IDF, LDA, Glove	TDE	600	TF-IDF, LDA, Glove
FPC	600	TF-IDF, LDA, Word2vec		300	LDA, Word2vec
	600	TF-IDF, LDA, Glove	DRIWL	300	LDA, Glove
FP2	300	TF-IDF, LDA, Word2vec	DTE	300 +	LDA, Glove
FP2	300	TF-IDF, LDA, Glove	WTE	300 +	LDA, Glove

The upper right corner of the model with “” indicates that this model uses Glove as the word embedding model. And, the dim represents the dimension of the final document representation vector.
