Document classification

This chapter will be looking at text classification using Keras. The dataset we will use is included in the Keras library. As we have done in previous chapters, we will use traditional machine learning techniques to create a benchmark before applying a deep learning algorithm. The reason for this is to show how deep learning models perform against other techniques.

The Reuters dataset

We will use the Reuters dataset, which can be accessed through a function in the Keras library. This dataset has 11,228 records with 46 categories. To see more information about this dataset, run the following code:

library(keras)
?dataset_reuters

Although the Reuters dataset can be accessed from Keras, it is not in a format...
