Perseverance in the Neural-Network Winter
From the late 1980s to the early 2000s, the AI field widely held that the neural-network technical path was hard to scale and limited in effect, and turned its research focus to other methods, but Hinton firmly believed multi-layer neural networks held potential not yet fully tapped, and in the long era called the "neural network winter" continued to work this then-unfavored direction; his 2006 research on deep belief networks was the key fruit of this perseverance, planting the seed for the later full revival of deep learning.
AlexNet: The Deep Network That Made Its Name in One Battle
In 2012, the deep convolutional neural network "AlexNet" designed by Hinton’s two graduate students Krizhevsky and Sutskever won the ImageNet image-recognition competition founded and hosted by Stanford’s Fei-Fei Li by an error rate nearly 11 percentage points lower than the runner-up, this stark advantage shaking the whole field of computer vision and machine learning, and within a few short years deep learning swiftly replaced the earlier mainstream methods to become the default technical path of almost all AI research and industrial application.
