1. A synaptic processor for use in constructing artificial neurons, comprising: a memory device for storing values of first and second expectations, initial values of said first and second expectations, values of a maximum expectation, and an equilibrium expectation, said values of said first and second expectations being bounded by said values of said maximum and equilibrium expectations; a Neuroprocessor connected to said memory device and being programmed to read said initial values of said first and second expectations from said memory device, to initialize said first and second expectations to said initial values, to receive an input signal, to modify said first expectation as a function of said input signal and said second expectation, to modify said second expectation in response to said first expectation, and to store the values of said first and second expectations in said memory device; and to generate a result signal as a function of said first expectation.
