3 Text embeddings

This chapter covers

Preparing texts for deep learning using word and document embeddings
Using self-developed vs. pretrained embeddings
Implementing word similarity with Word2Vec
Retrieving documents using Doc2Vec

After reading this chapter, you will have a practical command of basic and popular text embedding algorithms, and you will have developed insight into how to use embeddings for NLP. We will go through a number of concrete scenarios to reach that goal. But first, let’s review the basics of embeddings.

3.1 Embeddings

Embeddings are procedures for converting input data into vector representations. As mentioned in chapter 1, a vector is like a container (such as an array) containing numbers. Every vector lives in a multidimensional ...
