Content Data

This page contains data entry 65145 from the Axioma AXP content repository. The structured data below represents the complete record for this entry.

Geoff largely believes brains learn by gradient descent, but believes the mechanism by which gradients are estimated is not backpropagation, but some other (unknown) mechanism.

This has become a popular opinion of those who study credit assignment in the brain.

He has proposed several candidates for this mechanism, including feedback alignment (FA) and forward-forward (FF).

Some other candidates proposed by others are equilibrium propagation, predictive coding, and target propagation.
