My personal favorites are:
I'm sure there a ton of great sources I'm missing though and would love to hear thoughts from the community!
Also was pointed to this site via the FastAI courses, really cool visualizations. In particular the image kernels interactive visualization is the best way to present convolutions I've seen!
Kdnuggests has good articles on AI/ML as well: https://www.kdnuggets.com/news/index.html
I highly recommend signing up for NYU's data science newsletter. It covers major data science news and research from industry and academia, links to blogs and papers, and lists upcoming data science events and conferences. I've found it to be a great resource for staying up to date on what's going on in the field.
