I just landed in Boston…giving my commencement speech at MIT tomorrow and I had the thought, “I wonder if I need a dress shirt for this” and, yall, I do.

Attractors in ANNs mog attractors in brains

Our paper in @natcomms.nature.com, we show how cognitive maps in the hippocampal system could solve the general problem of representing and relating multiple alternative action plans.

Distinct synaptic plasticity rules operate across dendritic compartments in vivo during learning Synaptic plasticity underlies learning by modifying specific synaptic inputs to reshape neural activity and behavior. However, the rules governing which synapses will undergo different forms of plasti...

Our new paper is out in Science.

What is the synaptic plasticity rule in the brain, we asked. It turns out there are multiple, even within individual neurons.

Congrats Jake!

A neural mechanism for learning from delayed postingestive feedback - Nature Illness signals from the gut reactivate and strengthen flavour representations in the amygdala to support learning from delayed postingestive feedback.

How do we associate the flavors we experience during a meal 🍽️😋 with postingestive effects like food poisoning 🤢🤮 that arise much later?

Our answer in @nature.com this week: Illness signals from the gut reactivate and strengthen flavor representations in the amygdala.

The easiest experiment would be to graft shampoo with the step size schedule of whatever optimizer you are currently using

Train your model with an optimizer that orthogonalizes gradients (like muon or shampoo) and maybe everything gets cleaned up even more
