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.
A neural network comprising: a standard pattern associative memory network for storing at least one standard pattern; an input pattern network for receiving any given input pattern; a coordinate associated network for storing a predetermined restriction condition; and an association network which receives as inputs signals from said standard pattern associative memory network, said input pattern network, and said coordinate associated network, respectively, and which becomes active in accordance with a matching status between the input pattern and the standard pattern.

Claim 3
Dependent Claim

A neural network according to claim 1, wherein, in response to the signals from the coordinate associated network, the association network becomes active when the standard pattern matches a deflected version of the input pattern.
