This article recounts how Geoffrey Hinton persisted in his research for three decades during the AI winter, when neural networks were abandoned by academia. He eventually gained fame with AlexNet in the 2012 ImageNet competition and won the Nobel Prize in Physics in 2024.

Learning in Deep Networks under Dale's Constraint

arXiv cs.AI

This paper introduces a biologically motivated neural architecture that respects Dale's constraint—neurons and synapses have fixed sign—while still supporting backpropagation-like learning using non-negative error signals and local Hebbian updates, showing gains on Tiny ImageNet.
