Both brains and RNNs can re-use components of computation across similar tasks or contexts. But what exactly are those โ€œshared componentsโ€? How can they be used to solve several tasks? We address these questions in a new preprint with @avm.bsky.social! Link: www.biorxiv.org/content/10.6...

Interpretable compositional computation with recurrent neural networks

Flexible cognition utilizes reusable components to enable rapid adaptation of behavior to different contexts or tasks. Analysis of artificial neural networks trained on multiple tasks suggested that t...

What is the minimal machinery needed for complex, cognition-like behavior? With @lostintheswarm.bsky.social, we show how self-sustained calcium oscillations, diffusion, and mechanics may be enough to coordinate behavior across a single cell with no nervous system. www.biorxiv.org/content/10.6... 1/

If you use AI to help you peer review a paper, consider that >10 major concerns might be on the excessive side... In my view the reviewer's job is not to tell the authors what to do, but to evaluate the paper in front of them. If it's problematic, reject it!
