Abstract

Plural efferent signal paths paired with plural conventional afferent signal paths respectively are provided between lower order cell-layers and higher order cell-layers of a neural network model. Once an output response has been derived from the higher order cell-layer, an efferent signal is transmitted through the efferent signal path paired with the afferent signal path concerned in the output response. Under the control of which efferent signal, the afferent signal path contributing to the output response of the higher order cell-layer is affected by an excitatory effect, while the afferent signal path not contributing to the same is affected by an inhibitory effect. Hence the information processing consisting of both the associative memory and the pattern recognition provided with the faculty of segmentation can be attained despite deformation and positional error of the input pattern.
