Is there an RSS feed?
I asked for Atom/RSS about a year ago https://github.com/paperswithcode/paperswithcode-data/issues..., when the original paperswithcode feed disappeared.
It's a kind of coincidence that my own Atom feed of arXiv papers with code went live a few days ago https://code-available-feed.github.io/code-available-feed/.
It's independenent from Hugginface, and uses arXiv API directly. The code is open source, Apache 2. No AI is involved in parsing the arXiv pdfs, only a pattern match for known code-hosting domains like github.com or gitlab.com. This means there false positives, but that's probably fine, and their patterns could be tuned later.
You can host your own feed, by forking the repo and setting GitHub Actions environment variables. For now I'm hosting cs.AI and cs.SD categories.
I don't get the idea of "trending" for scientific papers. I would like to see the full list of papers that have associated source code from the given research field, like the arXiv cs.SD category. The reason to see all papers is to get an overview of the field.
