This is a great start. However, I love to attach narratives to problems, and have always enjoyed the coding competition questions where they tell a little scenario (albeit contrived) that usually have to do with something like a farmer and her cows in a barn or bees flying to pollen. It seems to somehow engage my mind more with the problem. Anyways, It would be great if there was some sort of 'problem description' and a background story context to really get the learner excited about applying the machine learning tool to solve real (fictional) life problems that are affecting real (fictional) people. And just to dream, maybe a comic edition like codecomics does with react, or learning mysql with nostarchpress manga comics.
