It claims to start from "bedrock" but beings with a Horace He post that clearly assumes you've done this before. Its fine if you want to be an intermediate course, but you should begin by defining your audience, so that you can reach the correct audience. You should have a section explaining who this is for, and if its _not_ an intro course, you should say that (and probably avoid terms like "fundamentals" and "bedrock").

Or if this is an oversight and you intend this actually be a course that starts from zero, you shouldn't start with an article that's starts off talking about training loss, test loss, and overfitting, without defining those terms.
