Nobel Prize in Physics 2024: John Hopfield and Geoffrey Hinton for machine learning with neural networks
On 8 October 2024, the Royal Swedish Academy of Sciences awarded the Nobel Prize in Physics 2024 to John J. Hopfield and Geoffrey Hinton for foundational work enabling machine learning with artificial neural networks.
Summary
On 8 October 2024, the Royal Swedish Academy of Sciences awarded the Nobel Prize in Physics 2024 to John J. Hopfield (Princeton University, USA) and Geoffrey Hinton (University of Toronto, Canada) 'for foundational discoveries and inventions that enable machine learning with artificial neural networks'. Hopfield created an associative memory, the Hopfield network, that can store and reconstruct patterns, using physics that describes atomic spin. Hinton used the Hopfield network as the basis for the Boltzmann machine, drawing on statistical physics. The prize of 11 million Swedish kronor is shared equally.
