Artificial Vision by Deep CNN Neocognitron
Kunihiko Fukushima
Abstract
Deep convolutional neural networks (deep CNNs) show a large power for robust recognition of visual patterns. The neocognitron, which was first proposed by Fukushima (1979), is recognized as the origin of deep CNNs. Its architecture was suggested by the neurophysiological findings on the visual systems of mammals. It acquires the ability to recognize visual patterns robustly through learning. Although the neocognitron has a long history, improvements of the network are still continuing. This article discusses the recent neocognitron, focusing on differences from the conventional deep CNNs. Some other functions of the visual system can also be realized by networks extended from the neocognitron, for example, recognition of partly occluded patterns, the mechanism of selective attention, and so on.
