Machine Learning in 2025: What learning resources have helped you most, and what are you looking forward to learning for the future?

What are some courses, video tutorials, books, websites, etc. that have helped you the most with your Machine Learning journey, and what concepts or resources are you looking forward to learning or using for future-proofing yourself in the industry?

So far I have heard a lot about Andrew Ng, so his courses are at the top of my list, but I would like to compile a more exhaustive list of resources so that I can better understand important topics and improve my skills, and hopefully this can be a way for others to do the same.

I'll start it off by posting the book I am currently following called "Zero to Mastery Learn PyTorch for Deep Learning" (https://www.learnpytorch.io/). It's free and pretty good so far.

I am probably starting way too far ahead as a complete beginner with this book, but I wanted to get a head start on learning PyTorch before learning the math, algorithms, and other more fundamental topics.
