Everywhere we go online nowadays seems to be followed by something like “your top picks” or “based on your previous…”; these Netflix movies that appear more often, or Spotify songs that keep showing up on your song radio are a result of recommender systems.

The type of natural language processing is called text classification. Much of the work here is from Lesson 8 of the FastAI course which, I cannot recommend enough to anyone interested in deep learning. Follow along with the notebook used to train the model.


Text is a pretty abstract concept to a computer that only…
