The neocognitron is a neural network that consists of many layers of partially connected cells. A new neocognitron architecture called the multilayer neocognitron with backpropagation learning (MNEOBP) is proposed, and it is shown that the original Neocognitron that is learned by backpropagation is a special case of what is proposed here. The MNEOBP has a number of advantages: (1) The algorithm for the MNEOBP is four times faster than the earlier algorithm since the number of cells calculated is reduced by a factor of four. (2) During the learning process, the mask (kernel) size is changed, this can speed up the training time by almost a factor of three. (3) The MNEOBP architecture can be implemented with a new digital neural network VLSI chip set called the Vision Processor (ViP). The ViP exploits the convolution structure of the network and can process a single 32 X 32 input layer in only 25.6 microsecond(s) with an 8 X 8 receptive field kernel.
