Flow Equivariant Recurrent Neural Networks - Kempner Institute
Sequence transformations, like visual motion, dominate the world around us, but are poorly handled by current models. We introduce the first flow equivariant models that respect these motion symmetrie...

(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.

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.

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!

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). 🤓
