Who they are

Geoffrey Hinton (1947– ) is a British-Canadian computer scientist and cognitive psychologist who in 1986, with David Rumelhart and Ronald Williams, co-authored a paper systematically expounding the application of the "backpropagation algorithm" to the training of multi-layer neural networks, and this method of adjusting network weights by passing error gradients backward layer by layer thereafter became the core mechanism of the training of almost all deep neural networks. In the decades-long "neural network winter," when the mainstream field had largely turned to other technical paths, Hinton held always to the neural-network direction, publishing in 2006 papers on "deep belief networks" that found a more effective initialization for the multi-layer training of neural networks, widely seen as the starting point of the "deep learning revival." In 2012 the AlexNet he designed with two graduate students, Alex Krizhevsky and Ilya Sutskever, won the ImageNet image-recognition competition by an enormous margin over the runner-up, the first time deep learning proved its overwhelming advantage over the earlier mainstream methods in an authoritative public competition, thereafter triggering the whole field of AI to turn collectively to deep learning. For these foundational contributions Hinton, with Bengio and LeCun, won in 2018 the Turing Award, and in 2024 further won the Nobel Prize in Physics (shared with John Hopfield for their foundational research in machine learning with artificial neural networks). In 2023 he actively resigned his post at Google, frankly saying he resigned to be able to speak more freely about the possible long-term risks of AI, and has since continually called on all sectors of society to face these risks squarely.

Key stories

Perseverance in the Neural-Network Winter

From the late 1980s to the early 2000s, the AI field widely held the neural-network path hard to scale and limited in effect, and mainstream funding and talent turned to other statistical-learning methods such as support vector machines, but Hinton held always that the potential of neural networks was not yet fully tapped. He described those years as feeling "like defending something no one believed in," and this decades-long perseverance was at last dramatically rewarded at the 2012 ImageNet competition.

Resigning from Google Just to "Speak Freely"

When Hinton resigned from Google in 2023 he said publicly the decision was to be able to speak freely about the potential risks of AI without the constraint of an employer’s interest, and this posture of "retiring after success and turning to warning" was thereafter widely reported and discussed by the media. He has since said many times publicly that he feels both excited and uneasy about the pace of deep learning’s recent development, holding that society’s attention to the risk of loss of control such systems may bring is still far from enough.
