I’ve been watching a lecture series by the infamous Andrej Karpathy on neural networks. Andrej worked closely with the AI / computer vision team at Tesla, co-founded OpenAI, and has taught several AI courses at Stanford.
He’s a great teacher, and each video in the series is very dense and thorough. If you’re interested in learning PyTorch and the basic mechanics of neural networks, this YouTube playlist is a great place to start.
