Geeky is Awesome: Word embeddings: How word2vec and GloVe …

Mar 04, 2017·word2vec is based on one of two flavours: The continuous bag of words model (CBOW) and the skip-gram model. CBOW is a neural network that is trained to predict which word fits in a gap in a sentence. For example, given the partial sentence "the ___ on the", the neural network predicts that "sat" has a high probability of filling the gap.
