    • A neuron unit processes a plurality of binary input signals and outputs a neuron output signal which is indicative of a result of the processing. The neuron unit is provided with a plurality of first gates respectively for carrying out a logical operation on a binary input signal and a weighting coefficient, a second gate for carrying out a logical operation on an excitatory output signal of each of the first gates, a third gate for carrying out a logic operation on an inhibitory output signal of each of the first gates, a fourth gate for synthesizing output signals of the second and third gates and outputting the neuron output signal, and a generating circuit for generating the weighting coefficients which are supplied to each of the first gates. The generating circuit for generating one weighting coefficient includes a random number generator for generating random numbers, and a comparator for comparing each random number r with a predetermined value q and for outputting a pulse signal having first and second values depending on whether each random number r is such that r.ltoreq.q or r>q, and each weighting coefficient is described by a pulse density.

    • A hierarchical signal processing apparatus includes aggregates having logic operation portions. The apparatus compares a final output signal from a logic operation portion in a final aggregate with a teaching signal, and generates an error signal by taking a signal which exists only in the teaching signal as a positive error signal, and taking a signal which exists only in said final output signal as a negative error signal. An error signal generating portion in the apparatus generates a positive error signal of a logic operating portion within a certain aggregate which supplies one or more output signals thereof to said logic operation means of another aggregate based on one or more logic operations on the excitatory weight function signal of said weight function signal, the positive error signal, the inhibitory weight function signal of said weight function signal and the negative error signal, and also generates a negative error signal of said logic operation means within said certain aggregate which supplies one or more output signals thereof to said logic operation means of said other aggregate based on one or more logic operations on the inhibitory weight function signal of said weight function signal, the positive error signal of said other aggregate, the excitatory weight function signal of said weight function signal and the negative error signal.
