Ask HN: Where can I find AI/ML math resources?

I'm diving into artificial intelligence and machine learning. In preparation for auditing a course in the spring, I want to focus on understanding as much of the math behind it as I can over the next few months. The professor who'll be teaching the course recommended I brush up on the following:

* discrete mathematics (set theory, counting, etc.)

* vectors and matrices

* a basic primer on probability and stats

(She also included concepts from basic calculus, but I'm not including those because I feel pretty comfortable reviewing that stuff.)

I'm looking for lecture videos, texts, and maybe some tutorials. Yes, I know how to google this stuff, but I'm seeing if folks can help me identify the really top-notch stuff. Thanks!
