New in the #DeeperLearningBlog: #KempnerInstitute research fellow @andykeller.bsky.social introduces the first flow equivariant neural networks, which reflect motion symmetries, greatly enhancing generalization and sequence modeling. bit.ly/451fQ48 #AI #NeuroAI

(1/7) New preprint from Rajan lab! 🧠🤖 @ryanpaulbadman1.bsky.social & Riley Simmons-Edler show–through cog sci, neuro & ethology–how an AI agent with fewer ‘neurons’ than an insect can forage, find safety & dodge predators in a virtual world. Here's what we built Preprint: arxiv.org/pdf/2506.06981

What shapes the topography of high-level visual cortex? Excited to share a new pre-print addressing this question with connectivity-constrained interactive topographic networks, titled "Retinotopic scaffolding of high-level vision", w/ Marlene Behrmann & David Plaut. 🧵 ↓ 1/n

Are you an RL PhD at Harvard who has had your funding wrecked by the government and working on topics related to multi-agent? Reach out, I am happy to try to find a way to support you.

Looking forward to presenting our work on cortico-hippocampal coupling and wave-wave interactions as a basis for some core human cognitions 5pm May 6th EST (US) 8am May 7th AEST (Sydney) Zoom link: columbiacuimc.zoom.us/j/92736430185 Thanks to WaveClub conveners Erfan Zabeh & Uma Mohan

It’s another big day for the #KempnerInstitute at @CosyneMeeting! Check out our work highlighted in poster session 3 today! #COSYNE2025

Super interesting thread!

Traveling waves of neural activity are observed all over the brain. Can they be used to augment neural networks? I am thrilled to share our new work, "Traveling Waves Integrate Spatial Information Through Time" with @andykeller.bsky.social! 1/13

Really interesting RNN work. And based on some spiking simulations I've tinkered with, it seems plausible that PV, CB & CR interneurons can contribute to changing the boundary conditions and the 'elasticity' of the oscillating 'rubber sheet' of cortex (and probably hippocampus and amygdala too). 🤓

In the physical world, almost all information is transmitted through traveling waves -- why should it be any different in your neural network? Super excited to share recent work with the brilliant @mozesjacobs.bsky.social: "Traveling Waves Integrate Spatial Information Through Time" 1/14

New research shows neurons learn to encode and transmit information to other spatially distant neurons through traveling waves. Read more in the #KempnerInstitute’s blog: bit.ly/3DrIPEq
