MyClass.py The result is a set of word-vectors where vectors close together in vector space have similar meanings based on context, and word-vectors distant to each other have differing meanings. original word2vec implementation via self.wv.save_word2vec_format getitem () instead`, for such uses.) And 20-way classification: This time pretrained embeddings do better than Word2Vec and Naive Bayes does really well, otherwise same as before. Word embedding refers to the numeric representations of words. This saved model can be loaded again using load(), which supports word counts. so you need to have run word2vec with hs=1 and negative=0 for this to work. Copy all the existing weights, and reset the weights for the newly added vocabulary. Why does a *smaller* Keras model run out of memory?
