Artificial intelligence pioneers and neuroscientists John Hopfield and Geoffrey Hinton have been awarded the 2024 Nobel Prize in Physics for their discoveries in AI.
On Tuesday, both visionaries were awarded the prize in Stockholm by Hans Ellegren, Secretary General of the Royal Swedish Academy of Sciences.
Both scientists have made significant contributions to understanding how the brain processes information and developing technologies inspired by these processes. Through their respective research, they have laid the groundwork for various AI and machine learning technologies used today.
Dr Hopfield, who conducts research at Princeton University in the United States developed the Hopfield network in 1982, a type of artificial neural network. This provided a theoretical foundation for the study of neural networks in AI and computational neuroscience.
On the other hand, Dr Hinton, often referred to as one of the ‘Godfathers of AI’, is known for the backpropagation algorithm, which was crucial to the development of deep learning models. Now, these networks are used to recognise images, correct mistakes, and optimise functions in computer science.
In 2012, Dr Hinton and his students developed the AlexNet model, revolutionising computer vision, won the ImageNet competition and sparked the modern AI revolution.
He spent the last 10 years working on AI at Google until his resignation last year. He stepped down after joining a number of ex-tech employees who warned about the potential dangers of these systems.
Ellen Moons, chair of the Nobel Committee for Physics noted that their discoveries and inventions “form the building blocks of machine learning that can aid humans in making faster and more reliable decisions, for instance when diagnosing medical conditions.”
In comments made to journalists, Dr Hinton compared AI-driven advancements to the Industrial Revolution. “But instead of exceeding people in physical strength, it’s going to exceed people in intellectual ability.”
While acknowledging that this would benefit society, he recognised that this could bear a threat of “things getting out of control.”
Dr Hinton remarked that he is a big fan of ChatGPT, particularly GPT-4, which he uses frequently not to give him answers to anything.
