A lot of machine learning algorithms can not deal with categorical data (like "favorite color" or "country code") directly. As a result, we have translate them into some sort of numerical value. The most common practice is to use something called One-Hot-Encoding, which is fine if you don't have many options for each category. However, if you have a lot of options, things get out of hand quickly. This is where methods like Target Encoding really start to shine, so that's what we'll talk about today. We'll also have time for any question you might have for me and maybe even a few silly songs! TRIPLE BAM!!!
