1. A signal processing system, including a network of neural operators pilot controlled by a control unit, each neural operator being operable to perform a multilinear function bearing on at least one input vector made up of a plurality of input variables, said function defining an activity of said operator, said input variables being representative of at least one of input signals of the system and of activities of other operators of the network, said system comprising: memorization means being addressable by said control unit and organized into a plurality of memory spaces respectively associated with said operators, each memory space containing, at an activity address, an activity value provided by the operator associated with the memory space, and, for at least one subset of the operators of the network, said associated memory spaces containing values of addresses of the variables that make up the input vectors of the operators of said subset, said values of addresses being modifiable by said control unit to enable dynamic reconfiguration of interconnections between said neural operators of said network.
