Welcome to Phase 2 of my No Black Box Machine Learning Course in JavaScript. It’s a course where we code without using libraries because it’s the best way to learn all inner workings of a machine learning system and you’ll greatly improve your software development skills as well.

The goal in this course is to build a web app that learns to recognize drawings. In this video, I first review the code from Phase 1 and several homework assignments. Then, we move to the topic of Data Cleaning. We learn how to build a tool to accomplish the job easier.
