The Usenix conference proceedings and other publications are usually very good: https://www.usenix.org/publications

I was an on-and-off-again ACM member for 40 years, and one of the better publications was ACM Computing Surveys: https://dl.acm.org/journal/csur -- even older issues are pretty high value, and there are tons of references to follow.

[edit: update Usenix link to something much more current]

You can go to Semantic Sanity and set up feeds of papers which you can seed with example papers. I’ve found some great (I.e. highly relevant to my projects) ML papers this way

I have a few interests that I randomly search for on arXiv.org and try to stay on top of.

Sometimes I will just randomly see what has been posted to one of the areas I am interested in as well on arxiv.

Then often I end up just googling references in the paper to other papers.

It can depend on your research interests, but Google Scholar is my go to first dip into any topic. Then its a bit of rabbit-holing by looking at cited sources and reading them or reading other papers that were a part of the same journal/conference.
