Summary

In this chapter, we introduced text processing and the bag of words technique. We then used this technique to build a spam detector for YouTube comments. Next, we learned about the sophisticated Word2Vec model and put it to task with a coding project that detects positive and negative product, restaurant, and movie reviews. That's the end of this chapter about text.

In the next chapter, we're going to look at deep learning, which is a popular technique that's used in neural networks.
