Understanding causes is key to science. Finite observational data alone isn't enough. While Bayes offers a framework to deal with this, the calculations are often intractable. We introduce a method to accurately approximate the posterior over causal structures. #ICLR2025 🧵1/15
Excited to be presenting this work at #ICLR2025. Please do reach out if you are interested in a similar space! 🗓️: Hall 3 + Hall 2B #471 🕐: Fri 25 Apr, 3 p.m. 📜: openreview.net/forum?id=eeJz7… This was a great collaboration w/ @_MatthewAshman, @jamesrequeima, @markvanderwilk
After using Deep Research for a while, I finally get the "it's just slop" complaint people have about AI art. Because I don't care much about art, most AI art seems pretty good to me. But information is something where I'm much closer to a connoisseur, and Deep Research is just…
I agree with @AmandaAskell. It is a fallacy. It can be appropriate to say both a) that LLMs are next-token predictors, at a mechanistic level, and b) that they have understanding, at another level. (a) is an engineering fact. But the negation of (b) does not follow. 1/2

I'm recruiting a new PhD student on Gaussian Belief Propagation for Spatial AI. For this particular opportunity: 1. The funding I have is only available to a student who qualifies for "home fees" in England; 2. I'm looking for someone who can start soon, ideally April 2025.
Within 2025, I will be hiring several PhD candidates and Postdoctoral researchers @ICComputing to work on various aspects of #TopologicalDeepLearning (#TDL). Posts are attached. The postdoc positions are also available to apply under: imperial.ac.uk/jobs/search-jo… #CVPR #CVML #AI #ML
Simultaneously funny and very relevant question… (Answer: no it doesn’t. But what’s missing, exactly?)

Test sets are the "get out of jail free" card of ML. It allows us to apply any crazy statistically-unprincipled method, and simply check if the predictions are good. But, it's easy to forget that holdout estimates themselves rely on assumptions that can be violated in practice!

A Gaussian Process regression model built on top of protein language model embeddings and inverse folding models makes accurate predictions with calibrated uncertainties. @WouterBoomsmaDK
