I had forgotten about this youtube channel for a while, but it's pretty great:

as a sometime ML student, I have a casual interest in practical data munging techniques. AI Coffee Break is great for getting me a basic understanding of fairly complicated concepts and tools without a lot of upfront work learning lower-level stuff. For the most part, I understand the concepts at the level they're discussed using not much more than my undergrad-level knowledge.
