Remembering an image is one thing, but interpreting what it depicts requires a little more.

Newly awarded physics laureate Geoffrey Hinton had studied experimental psychology and artificial intelligence and was wondering whether machines could learn to process patterns in a similar way to humans, finding their own categories for sorting and interpreting information. Hinton started from a network developed by his co-laureate John Hopfield and expanded it to build something new, using ideas from statistical physics.

Hinton used the Hopfield network as the foundation for a new network that uses a different method: the Boltzmann machine. This can learn to recognise characteristic elements in a given type of data. Hinton used tools from statistical physics, the science of systems built from many similar components. The machine is trained by feeding it examples that are very likely to arise when the machine is run.

The Boltzmann machine can be used to classify images or create new examples of the type of pattern on which it was trained. Hinton has built upon this work, helping initiate the current explosive development of machine learning.

The 2024 Nobel Prize in Physics has been awarded to John J. Hopfield and Geoffrey E. Hinton “for foundational discoveries and inventions that enable machine learning with artificial neural networks.”

BREAKING NEWS
The Royal Swedish Academy of Sciences has decided to award the 2024 Nobel Prize in Physics to John J. Hopfield and Geoffrey E. Hinton “for foundational discoveries and inventions that enable machine learning with artificial neural networks.”

This year’s two Nobel Prize laureates in physics have used tools from physics to develop methods that are the foundation of today’s powerful machine learning. John Hopfield created an associative memory that can store and reconstruct images and other types of patterns in data. Geoffrey Hinton invented a method that can autonomously find properties in data, and so perform tasks such as identifying specific elements in pictures.
