    This paper dramatically changed my understanding of how to think about the internal representations of models. Check it out :)

    Interpreting and controlling internal representations should be based on how the model actually uses them! Turns out: information geometry makes this precise. We show how, and use it to derive a (provably & empirically) robust strategy for steering. arxiv.org/abs/2602.15293

    There's an idea that LLMs encode high-level concepts linearly in representation space, and that these can be understood using geometric operations (e.g., cosine similarity) But: What does "linear" even mean? And, why would (Euclidean) geometry encode meaning?

    Fundamentally, high-level concepts group into categorical variables---mammal, reptile, fish, bird---with a semantic hierarchy---poodle is a dog is a mammal is an animal. How do LLMs internally represent this structure? arxiv.org/abs/2406.01506

    Though it's an odd moment for good news, I'm incredibly excited that 1. I'm joining the University of Chicago as an assistant professor of stats/data science on January 1st, and 2. I'll be joining Google as a research scientist until then

    The idea that it's wrong to publicly point out flaws in high-profile published papers seems totally nuts to me.

    Could anyone look at this and a slaughterhouse and conclude that the slaughterhouse is _better_?

    In ML, spurious correlations are know-it-when-you-see-it; e.g., changing โ€œAlice rules!โ€ to โ€œBob rules!โ€ changes predicted sentiment. Such ad-hoc tests are intuitive, but hard to connect to standard practice. Turns out, causality has a lot to say! arxiv.org/abs/2106.00545

    One of my papers was accepted as a NeurIPS spotlight. I'm happy about it. Still, I wish we spent more time celebrating science than the game. And, my view is unchanged: the machine learning review process is badly broken.

    Does it violate any NeurIPS policies to post (suitably censored) review screenshots to twitter? We got one that's so heroically passive aggressive that it's transcended into art

    Review for NeurIPS: a majority of the papers I got are so bad that the author's themselves could not have had a reasonable good faith belief the work was publication ready. There needs to be a disincentive for submitting garbage and hoping it sneaks through.

    Life is short. Do work that you're proud of and that you believe is important. And, if a project doesn't pan out---they often don't!---then abandon it and move on. This tweet brought to you by NeurIPS reviewing.

    NeurIPS bidding showed me ~100 papers on causality. I'm happy the area is so popular, but keeping up w/ the literature seems borderline impossible now.

    The secret to doing large, ambitious projects is to radically misestimate how long they'll take at the time when you commit to them.
