Y’all are reading this paper in the wrong way.

We love to trash dominant hypothesis, but we need to look for evidence against the manifold hypothesis elsewhere:

This elegant work doesn't show neural dynamics are high D, nor that we should stop using PCA

It’s quite the opposite!

“Our findings challenge the conventional focus on low-dimensional coding subspaces as a sufficient framework for understanding neural computations, demonstrating that dimensions previously considered task-irrelevant and accounting for little variance can have a critical role in driving behavior.”
Neural dynamics outside task-coding dimensions drive decision trajectories through transient amplification
Most behaviors involve neural dynamics in high-dimensional activity spaces. A common approach is to extract dimensions that capture task-related variability, such as those separating stimuli or choice...

📍Excited to share that our paper was selected as a Spotlight at #NeurIPS2025!

arxiv.org/pdf/2410.03972

It started from a question I kept running into:

When do RNNs trained on the same task converge/diverge in their solutions?

How foragers depart from optimal models can tell us a lot about how they compute their decisions.

A strong but underexplored departure is that foragers widely vary when they leave identical patches.

Is this something YOU ever ask yourself?

"Man, Brett Karlan (aka Old Jerry Fodor) claims to love Fodor, but has never published anything defending anything remotely Fodorian. What's up with that?"

This was a puzzle that long perplexed the scholars... until now!
