A great entry into the proposals available for physiologically plausible gradient descent!
I think the way they use dendrite targeting inhibition in this model is particularly elegant.
Time to start testing these ideas folks!!!

Our latest publication grapples with how the brain could implement gradient descent by sending learning targets top-down, gating plasticity with dendritic inhibition, and updating synaptic weights with biologically observed learning rules like BTSP.

New #NeuroAI #compneurosky preprint! To better understand how target-directed learning works in the brain, we sought to engineer an artificial neural network capable of solving complex image classification tasks that comprises only experimentally-supported biological building blocks. (1/15)
