John Hopfield and Geoffrey Hinton awarded 2024 Nobel prize in Physics

The Academy honored the scientists for foundational discoveries that enable machine learning with neural networks.

John Hopfield and Geoffrey Hinton have won the Nobel Prize in physics 2024 for their pioneering work in the field of machine learning.

The Royal Swedish Academy of Sciences said on Tuesday the scientists were honoured “for foundational discoveries and inventions that enable machine learning with artificial neural networks”.

Hopfield, whose research is carried out at Princeton University in the United States, was recognised for creating an associative memory that can store and reconstruct images and other types of patterns in data.

Hinton, who works at the University of Toronto, invented a method that can autonomously find properties in data, allowing it to perform tasks such as identifying specific elements in pictures.

“This year’s two Nobel Laureates in physics have used tools from physics to develop methods that are the foundation of today’s powerful machine learning,” the Nobel committee said in a press release.

“The laureates’ work has already been of the greatest benefit. In physics we use artificial neural networks in a vast range of areas, such as developing new materials with specific properties,” said Ellen Moons, chair of the Nobel Committee for Physics.

Such networks have also “become part of our daily lives, for instance in facial recognition and language translation,” she added.

However, the committee also noted the global concerns that surround machine learning and artificial intelligence.

“Collectively, humans carry the responsibility for using this new technology in a safe and ethical way for the greatest benefit of humankind,” Moons added.

Hinton has previously acted upon such fears. He quit a role at Google so he could more freely speak about the dangers of the technology he helped create.

He reiterated his doubts on Tuesday as he told the committee by phone that he was “flabbergasted” by the award.

The researcher said that he continues to worry “about a number of possible bad consequences” of his machine learning work, “particularly the threat of these things getting out of control”.

However, he added that he would still do it all over again.

The Nobel Prize is one of the world’s most prestigious awards, established by the will of Alfred Nobel, the inventor of dynamite, in 1895. 

The prize recognises individuals or groups for significant contributions in six categories: 

1. Peace, 

2. Literature, 

3. Chemistry 

4. Physics 

5. Physiology or Medicine

6.  Economic Sciences. 

The awards are presented annually in Stockholm, Sweden, except for the Peace Prize, which is awarded in Oslo, Norway. Each laureate receives a medal, a diploma, and a cash prize.
