For years, RS_c treated X/Twitter as the natural place to ship RecSys news. You published a post, dropped a link, added #recsys, and the right people would see it. Lately, though, that loop has been breaking. So, we move to #LinkedIn...

Great to see how important #recsys is for #NVIDIA's CEO Jensen Huang recommender-systems.com/news… #RS_c
A new book on #recsys. Well-written and deep technical coverage of recsys algorithms:

Nice summary of resource consumption of #recsys algorithms by Michael Ekstrand. It would be great to see more charts like that in #recss publications.

Wonder what happened with the @LinkedIn recsys algo that now prioritizes 2-3w old posts that I have seen before. Congratulations!
#Yandex released a #recsys dataset with 5 billion interactions (1m users and 9m music tracks). Very interesting details such as timestamps, "organic", likes, dislikes, ... Seems highly interesting. Has anyone tried it already? recommender-systems.com/news… #Yambda
Is #RecSys on X dead?🤔 It feels like there's way less discussion and fewer posts these days, compared to a while ago (i.e. the pre-@elonmusk era). Did everyone migrate to LinkedIn? Or am I hallucinating?
