GloVe and Word Vectors for Sentiment Analysis - Salesforce

When it comes to producing good word vectors, GloVe is more similar to Word2vec than it is to our simple co-occurrence matrices. Rather than using SVD and other hacks, GloVe uses an objective function to train word vectors from the co-occurrence matrix. To understand this objective function, it helps to build it up, piece by piece. ...

Mar 01, 2019·The above embeddings of Glove are trained on a corpus of 6 Billion words. For NLP applications it is always better to go with the highest vector dimension if you have sufficient hardware to train on. In our example, we are using Glove with 300d and 100d word vectors. The results show that accuracy with 300d is much better than 100d.
