The learning algorithms within neocognitron are discussed in this paper. Neocognitron is a neural network model that has two distinctive types of cells: S-cells and C-cells. The prime use of this type of neural network is in the imitation of the visual cortex system. The paper does not present any comparisons between neocognitron-type neural networks and other models used for pattern recognition, such as Hopfield neural nets.

The paper presents neocognitron learning mechanisms that have incremental learning capabilities. The author proposes a learning method and network architecture. The algorithms and the network behavior were tested through a computer simulation examining the scale of the network, and the recognition rate.

The analysis of the experimental results is somewhat limited, and does not clearly demonstrate the benefits of the new incremental capabilities. The author might consider doing more experiments in addition to the limited number of experiments presented here. The list of references was also rather short. In addition, the author made reference to his own work four times, in 14 listed references.
