Word Embeddings

In the previous chapter, we talked about convolutional networks, which have been very successful against image data. Over the next few chapters, we will switch tracks to focus on strategies and networks to handle text data.

In this chapter, we will first look at the idea behind word embeddings, and then cover the two earliest implementations – Word2Vec and GloVe. We will learn how to build word embeddings from scratch using the popular library Gensim on our own corpus and navigate the embedding space we create.

We will also learn how to use pretrained third-party embeddings as a starting point for our own NLP tasks, such as spam detection, that is, learning to automatically detect unsolicited and unwanted emails. We will then ...
