Notice how the start of this chapter was an in-your-face algorithm? I wanted to make sure that the first thing you see is this formula. This underscores just how important it will become in your machine learning career. Write it down, put it on a sticky note on your monitor, or commit it to memory!

In this chapter, we will:

• Apply the famous Bayes' theorem to solve a very famous problem in computer science
• Show you how you can use Bayes' theorem and Naive Bayes to plot data, discover outliers from truth tables, and more
