Claim 1

An artificial, auto-associative memory storage device for retrievably storing a response together with an associated at least one input analog stimulus, each response and stimulus having respective ones of representative, pre-assigned complex polar values, said device comprising: a re-writable correlation substrate including a quantum of required physical storage space for storing a addressably mapped, congruous stimulus-response association thereon, wherein said association is thus stored as an initial correlation value which is the outer product of: the conjugate of the stimulus one of said preassigned values; and, the response one of said pre-assigned values, and, whereby said association represents a certain contemporaneous state of association between said input analog stimulus and said response; a data bus, for conveying data received by or transmitted from said storage device, to and from said substrate, said data bus being connected in data communicating relation with said substrate, whereby said correlation substrate is subsequently addressably re-written responsive to supervisory intervention input delivered through said bus as a congruency-enhancing association between said at least one input analog stimulus and a predetermined desired response, each having respective, representative ones of a pre-assigned subsequent stimuli and desired response complex polar values which are combined as an inner product of said subsequent stimulus value through said initial correlation value to yield a transformed response value having a measurable vector difference value from said desired response value, which vector difference value is in turn used to perform an element by element vector addition to said initial correlation value to yield said enhanced-correlation value; whereby, said enhanced, mapped association is stored on said substrate by replacing said initial correlation value with said enhanced correlation value, to thereby enhance the addressable information content stored within a quantum of re-written storage space equal in size to said quantum of required space.
