A deep convolutional neural network built by Alex Krizhevsky, Ilya Sutskever and Geoffrey Hinton that won the 2012 ImageNet contest by a wide margin. Its win set off the deep-learning era.
If it had been just five years later, it would have been 2012 and AlexNet would have been out. There would have been something I could point to that would say neural networks are coming back.
