How does the brain represent multiple different things at once in a single population of neurons? Justin Fine, Neuro Polarbear, Becket Ebitz, Seng Bum Michael Yoo and I show that it uses semi-orthogonal subspaces for each item. Preprint here: arxiv.org/abs/2309.07766 Tweets below! (1/n)
Imagine a model that unites predictive coding, sparse coding, and rate coding — all of 'em codings — under Bayesian inference. Wouldn't that be amazing? It’s already here: the Poisson Variational Autoencoder 👉🧵[1/n] w/ Dekel Galor & Jacob Yates 📜preprint: arxiv.org/abs/2405.14473
I am delighted to share our recent paper: arxiv.org/abs/2405.19681. It can be thought of as a version of the Bayesian Learning Rule, extended to the fully online setting. This was a super fun project with Peter Chang and the unstoppable Matt Jones (matt.colorado.edu). By

New Research (w/ amazing Hangfeng He) "A Law of Next-Token Prediction in Large Language Models" LLMs rely on NTP, but their internal mechanisms seem chaotic. It's difficult to discern how each layer processes data for NTP. Surprisingly, we discover a physics-like law on NTP:
