which has been popular recently as a substitute for word vectors so if you know word vectors were vectors are basically the kind of first stage in most language processing tasks where for each word say the cat sat something for each word you have you had a big giant table and for each word you associate a vector of fixed size dimension right so you place every word in a vector space and these vectors you pre compute for something like word Tyvek or glove and that gives you a nice way to basically deal with these words in a canonical way
