Re: How do you typically learn the material?
I typically watch each video only once, but I pause frequently to think about the concepts or to search about specific topics such as "Gradient Descent" or "Legendre Polynomials".
I found that the concepts, and most mathematical formulas and derivations, are remarkably well explained and I haven't had much need to look at the book (though I'm sure it will become a welcome reference).
I admit that a lot of the actual learning happens by doing the homework. This is when ideas, at least in my case, start to solidify, and when I have to address subtleties, that I hadn't even thought about, say in the definition of the "VC Dimension" or in the concept of "Deterministic Noise".
