An openness to experiment: contrary to popular perception bigtech’s money earning machines have not shifted over to LLMs but there is a top to down increase in the willingness to experiment new things. There is a lot more situational innovation in bigtech now.

A big change is coming in recsys. Long ago ranking models were actually ranking when it was doing pairwise ranking. Then it became an estimator model in the era of VM. Can we unlock all the RL advances of LLMs by making ranking a reward maximizing model again. open.substack.com/pub/recsysml...

#LLM vs #RecommenderSystems (Part 2/3) 👉 recsysml.substack.com/p/recsys-ret... is about Retrieval. And this is where the analogy with LLMs becomes surprisingly tight. Core idea: Retrieval in recommender systems plays the same role as pretraining in LLMs. We show clustering > "Semantic IDs"

For folks who are following the trend of “generative recommendations”, I’d love to know what you feel is the best ight version of semantic id in your domain. For instance if we were to build a feed ranking for Bluesky using generative recs what would the “semantic” id be?

Sometimes you see articles about child math prodigies that turn out to be them proving an aesthetically pleasing but useless bit of trivia, but this looks like the first case (since Tao?) of a 17-year old girl solving a major open problem in a single author paper english.elpais.com/science-tech...

60% of American households can’t afford a minimal quality of life. Meanwhile, the 19 richest households saw their wealth increase by $1 trillion in 2024 — the biggest one-year increase ever. Our problem isn't a lack of resources. Our problem is ever-expanding inequality.
