INFORMATION PROCESSING SYSTEM

An adaptive information processing system includes a module, called a Nestor module, having a plurality (N) of input terminals 1, 2 . . . , j . . . , N, adapted to receive N input signals s.sub.1, s.sub.2 . . . , s.sub.j . . . , S.sub.N, respectively, and a plurality (n) of output terminals 1, 2 . . . , i . . . , n, adapted to present n output responses r.sub.1, r.sub.2 . . . , r.sub.i . . . , r.sub.n, respectively. A plurality of junction elements, called mnemonders, couple various ones (or a multiplicity) of the input terminals with various ones (or a multiplicity) of the output terminals. These mnemonders provide a transfer of information from an input terminal j to an output terminal i in dependence upon the signal s.sub.j appearing at the input terminal j and upon the mnemonder transfer function A.sub.ij. Means are provided for modifying the transfer function A.sub.ij of the mnemonders in dependence upon the product of at least one of the input signals and one of the output responses of the Nestor module. In a preferred embodiment of the invention, the modification to the transfer function of each mnemonder takes the form: ##EQU1## WHERE .eta. IS A CONSTANT OF PROPORTIONALITY.
