New in @PNASNews: https://t.co/95Gs0QTYf4 We study how humans explore a 61-state environment with a stochastic region that mimics a “noisy-TV.” Results: Participants keep exploring the stochastic part even when it’s unhelpful, and novelty-seeking best explains this behavior.

Thrilled to see our TinyRNN paper in @nature! We show how tiny RNNs predict choices of individual subjects accurately while staying fully interpretable. This approach can transform how we model cognitive processes in both healthy and disordered decisions.

Excited to see our Centaur project out in @Nature. TL;DR: Centaur is a computational model that predicts and simulates human behavior for any experiment described in natural language.

First first-author paper now in @ScienceMagazine! Great thanks to incredible mentor @reziliusReza and coauthors @just_alden @pauliehage @HElseweifi. We asked how neurons in the cerebellar cortex control rapid eye movements (saccades). 1/3 https://t.co/5Cf5cGHlGa

Null space theory predicts that neurons generate spikes not only to produce behavior but also to prevent the undesirable effect of other neurons on behavior. In this work, we show that this competi...

I am pleased to announce a new version of my RL tutorial. Major update to the LLM chapter (eg DPO, GRPO, thinking), minor updates to the MARL and MBRL chapters and various sections (eg offline RL, DPG, etc). Enjoy! https://t.co/SjMdabl0yW

Thank you for featuring my work! 😃🥳🤩 I'm currently investigating more of the process mechanisms adopted by humans (and AI) in divergent thinking!
🧠🤖 New study led by @surabhisnath reveals striking parallels between human and AI creativity. Both people and LLMs use flexible and persistent strategies — but AI leans into one at a time. Pairing people with complementary LLMs could supercharge co-creation. 👉

Super excited to see my PhD thesis featured by EPFL! 🎓 It's such a great honor — thank you for sharing it with the world. 🚀🥰 P.S.: There's even a French version of the article! It feels so fancy! 😎 👨🎨 🇫🇷
🧠💻 A researcher from our school, working at the crossroads of neuroscience and computational science has developed an algorithm that can predict how surprise and novelty affect behavior. https://t.co/BHkaiwCWrd

To conclude, however crazy some radical behaviourist positions and claims may sound, I have to admit that I somehow admire their epistemological boldness and I seriously believe they must have been fun to hang out and argue with 🤓 end/n
