Jun 04, 2017·Now, a column can also be understood as word vector for the corresponding word in the matrix M. For example, the word vector for ‘lazy’ in the above matrix is [2,1] and so on.Here, the rows correspond to the documents in the corpus and the columns correspond to the tokens in the dictionary. The second row in the above matrix may be read as – D2 contains ‘lazy’: once, ‘Neeraj ...

What is Word Embedding | Word2Vec | GloVe

Jul 12, 2020·Word2vec is a method to efficiently create word embeddings by using a two-layer neural network. It was developed by Tomas Mikolov, et al. at Google in 2013 as a response to make the neural-network-based training of the embedding more efficient and since then has become the de facto standard for developing pre-trained word embedding.
