What was happening with this account? I was often seeing popular but empty (only title of the paper and maybe a short readme) repositories that were created directly after a paper was published?

Just part of the process - he'd queue up the projects as interesting things came in, then plow through. Usually he'd have a rough framework within a day or two, and then a working proof of concept within a week, and then return to the most promising, useful, or interesting projects.

I really appreciated his coding-style, but the bar is quite low on research/ML-algorithms to be fair. I still wonder how he managed to get „trending“ repositories regularly despite the repositories being empty.
