Our new preprint: 𝐅𝐞𝐚𝐭𝐮𝐫𝐞-𝐬𝐩𝐞𝐜𝐢𝐟𝐢𝐜 𝐭𝐡𝐫𝐞𝐚𝐭 𝐜𝐨𝐝𝐢𝐧𝐠 𝐢𝐧 𝐥𝐚𝐭𝐞𝐫𝐚𝐥 𝐬𝐞𝐩𝐭𝐮𝐦 𝐠𝐮𝐢𝐝𝐞𝐬 𝐝𝐞𝐟𝐞𝐧𝐬𝐢𝐯𝐞 𝐚𝐜𝐭𝐢𝐨𝐧. We describe how the LS guides defensive responses by forming critical computations built from functionally and molecularly distinct cells and their afferent inputs. www.researchsquare.com/article/rs-6...

Humans and animals can rapidly learn in new environments. What computations support this? We study the mechanisms of in-context reinforcement learning in transformers, and propose how episodic memory can support rapid learning. Work w/ @kanakarajanphd.bsky.social : arxiv.org/abs/2506.19686

🚀 An other Exciting news! Our paper "From Lazy to Rich: Exact Learning Dynamics in Deep Linear Networks" has been accepted at ICLR 2025! arxiv.org/abs/2409.14623 A thread on how relative weight initialization shapes learning dynamics in deep networks. 🧵 (1/9)

Already feeling #cosyne2025 withdrawal? Apply to the Flatiron Institute Junior Theoretical Neuroscience Workshop! Applications due April 14th jtnworkshop2025.flatironinstitute.org

Life update: I'm starting as faculty at Boston University @bucds.bsky.social in 2026! BU has SCHEMES for LM interpretability & analysis, I couldn't be more pumped to join a burgeoning supergroup w/ @najoung.bsky.social @amuuueller.bsky.social. Looking for my first students, so apply and reach out!

What are you plans for April 5th? Decide now which event you'll attend and who you'll bring along. See you in the streets! handsoff2025.com/about

I'll be presenting this at #cosyne2025 (poster 3-50)! I'll also be giving a talk at the "Collectively Emerged Timescales" workshop on this work, plus other projects on emergent dynamics in neural circuits. Looking forward to seeing everyone in 🇨🇦!

Our paper, “A Theory of Initialization’s Impact on Specialization,” has been accepted to ICLR 2025! openreview.net/forum?id=RQz... We shows how neural network can build specialized and shared representation depending on initialization, this has consequences in continual learning. (1/8)

We'll have a poster on this at #Cosyne2025 in the third poster session (3-055). Come say hi if you're curious!

How does barcode activity in the hippocampus enable precise and flexible memory? How does this relate to key-value memory systems? Our work (w/ Jack Lindsey, Larry Abbott, Dmitriy Aronov, @selmaan.bsky.social ) is now in eLife as a reviewed preprint: elifesciences.org/reviewed-pre...

We’re organizing a #CoSyNe2025 workshop on what agent models can teach us about neuroscience! See Sat’s thread for more info 😊

If you’re interested in foundation model approaches for combining EEG/EMG/ECG/EOG data, check out our work at the Neurips AIM-FM workshop tomorrow! This was work done with Apple’s Body-Sensing Intelligence Group 🧠 🤖 arxiv.org/abs/2410.16424
