The question is, though, if the expertise and intuition developed during, say, running XGboost classifiers at scale in AdTech really of much relevance when thinking about large transformer models trained with a self-supervised objective and RLHF?
If you try to study this in depth, these models can do something the usual "datascience"-tier ones commonly cannot: https://arxiv.org/abs/2205.10343 https://moultano.wordpress.com/2020/10/18/why-deep-learning-...
By the standards of AdTech, latent space stuff was pretty unproven when I left the game a few years ago.
Low-rank approximations were in some sense implicit in that, but were not at that time an explicit goal.
If I were doing an AdTech system from scratch I’d most likely reach for the kind of recommender systems that you’re alluding to sooner.
Sounds like you know your stuff :)
It’s possible that I’ve just fallen too far under the influence of Deutsch and Marletto, but as someone who has worked on systems like this I’m rather skeptical that one of these things is going to break the gridlock between quantum theory and general relatively any time soon.
There’s no reason why one couldn’t principle but I’ve babysat enough big ML systems that I tend to think in terms of “how do we keep this thing from shitting itself” rather than “damn this thing is going to win a Fields medal if I turn my back on it”.
