Abstract

To enable the pattern matching between a shifted input pattern and the standard pattern, a plurality of standard patterns are stored in a standard pattern associative memory network 12. A pattern shifted relative to the standard pattern is inputted to the input pattern network 11 and a restriction condition of when the input pattern is shifted relative to the standard pattern is stored in a coordinate associated network 14. In an association network 13, weights and biases are determined so that the respective units of the network 13 are activated most intensely when the input pattern and the standard pattern match correctly each other in response to the signals from the respective networks 11, 12, and 14.
