Chapter 5. Generating Text in the Style of an Example Text

In this chapter we’ll look at how we can use recurrent neural networks (RNNs) to generate text in the style of a body of text. This makes for fun demos. People have used this type of network to generate anything from names of babies to descriptions of colors. These demos are a good way to get comfortable with recurrent networks. RNNs have their practical uses too—later in the book we’ll use them to train a chatbot and build a recommender system for music based on harvested playlists, and RNNs have been used in production to track objects in video.

The recurrent neural network is a type of neural network that is helpful when working with time or sequences. We’ll first look at Project Gutenberg as a source of free books and download the collected works of William Shakespeare using some simple code. Next, we’ll use an RNN to produce texts that seem Shakespearean (if you don’t pay too much attention) by training the network on downloaded text. We’ll then repeat the trick on Python code, and see how to vary the output. Finally, since Python code has a predictable structure, we can look at which neurons fire on which bits of code and visualize the workings of our RNN.

The code for this chapter can be found in the following Python notebook:
