AI pioneers win Nobel Prize in physics

Hinton, 76, helped develop a technique in the 1980s known as backpropagation, instrumental in training machines how to ‘learn’ by fine-tuning errors until they disappear.

Two pioneers of artificial intelligence — John Hopfield and Geoffrey Hinton — won the Nobel Prize in physics Tuesday for helping create the building blocks of machine learning that is revolutionizing the way we work and live but also creates new threats for humanity.
