Associative pattern conversion system and adaptation method thereof

Claim 1

An associative pattern conversion system for allowing recognition of an input signal, said conversion system comprising: generating means for sensing an object and for generating input data which is representative of selected characteristics of said sensed object; a serial input/output memory element for storing a converting matrix capable of converting said input data to weighted data; matrix calculating means for performing a matrix calculation upon said converting matrix stored in said memory and said input data, thereby producing said weighted data; quantizing means for quantizing said weighted data produced by said matrix calculating means; adder means for adding said converting matrix and a second matrix and for generating an output matrix which is indicative of said adding, said adder means including means for multiplying said input data by a transposed matrix of said input data, thereby generating said second matrix; maximum limiting means for limiting each element of said output matrix generated by said adder means to a preselected maximum value; and recognition means for receiving said input signal, and for producing, based upon said input signal and said output matrix, an associated recognition signal.
