I will continue to proudly say I never use LLMs. Not for writing, not for coding, and certainly not for "art". Just haven't felt the need at all.

thrilled that we'll be presenting this paper as a spotlight at #ICML2025 . come by our poster in vancouver to chat with us about the use of LLMs for advancing neuroscience! here's the camera-ready version: openreview.net/forum?id=dhRXGโ€ฆ

really excited about this new work we just put out, led by my students Roger Creus Castanyer & Johan S. Obando ๐Ÿ‘๐Ÿฝ , where we examine the challenges of gradient propagation when scaling deep RL networks. roger & johan put in a lot of work and care in this work, check out more details in ๐Ÿงต๐Ÿ‘‡๐Ÿพ !

๐Ÿšจ Excite to share "Stable Gradients for Stable Learning at Scale in Deep Reinforcement Learning" work. ๐Ÿฅณ We tackle gradient instability in large deep RL networks, enabling stable and scalable learning with strong performance across the board. ๐Ÿ“„ Paper: arxiv.org/abs/2506.15544

B/f joining Brain in 2017 I interviewed with a startup doing smthg similar (w/ lots more manual effort). In intrvw I noticed a sleep pod & said "we have nap pods at Google also". They said "yeah, we regularly spend the full night at office"... I got the offer, but said no ๐Ÿ˜Š
