    RT @tyboydmeredith: Very excited to have posted a new preprint on my PhD work in the @brody_lab where we show that rats can achieve near-optimal time investment in a confidence-guided waiting task

    RT @SaxeLab: Check out our #ICLR2023 #physics4ml workshop paper with poster tomorrow. The RL Perceptron: A solvable model of high-D policy learning and generalisation with lots of follow up potential! Great fun with @nishpathead, @sebalexlee, @stefesseM and @sebastiangoldt
    Nishil Patel @nishpathead
    Excited to present “Dynamics of high-dimensional policy learning in RL” at #ICLR2023 #physics4ml workshop tomorrow! We have few tractable theories of high-D policy learning that address generalization, so we introduce a solvable model: the RL perceptron!

    RT @SaxeLab: Excited to share our new paper at #NeurIPS2022! Prior knowledge deeply impacts learning dynamics. We derive exact solutions in deep linear networks for a rich class of initialisations. Paper: Poster: Nov 29 11-1 Hall J #511 A 🧵…

    So excited and happy that this is finally out: A big chunk of my PhD with loads of fun results! If you happen to be at #NeurIPS2022 make sure to come to Hall J - Poster #511 on Tuesday, where @ClementineDomi6 will present our work!

    So Meta AI (aka Facebook research) came up with a large language model for science: And I came up with a game: Ask it for the theorem that you have proved! Anyone out there who can explain my theorem to me? Does it even make sense?

    Do you know this feeling right between satisfaction and despair when weeks of work reduce to a couple sentences while writing up a paper?

    Come and join us! If you have questions about what we do, how we do it, how it is to live in the UK ... and how it is to work with Andrew (spoiler: he is a 5 out of 5 stars advisor) feel free to drop me a line

    RT @SaxeLab: “The Neural Race Reduction: Dynamics of abstraction in gated networks” New paper @icmlconf We derive reductions and occasionally exact explicit solutions for the learning dynamics of a class of nonlinear deep networks in the rich representation learning regime.

    Is there any better environment to present work on gradient-based optimisation than this? I don't think so! I am feeling very happy and privileged to be part of the #Leshouches2022 summer school on statistical physics & machine learning :)

    RT @SaxeLab: Saxelab is hiring it’s first *experimental* postdoc or research scientist! We aim to understand how representations change in multi-layered neural systems, to test links between modern deep learning and biological learning. We’re at #cosyne22 or always happy to chat! 👇

    The result of environmentally harmful subsidies and taxes: Flight 5€ vs Train 176€. I am privileged/enduring enough to take the train but I know that many are not. Let's start taxing kerosene/airlines properly such that prices create an incentive to make the right choice - now!
