Abstract
An artificial neuron is provided using a simple distance calculation between the input signal vector and the synapse weight signals for providing an output signal. A difference signal is developed by subtracting a weight signal from an input signal. The difference signal is processed through a weighting function having a predetermined polarity and accumulated for providing the output signal of the neuron. A digital embodiment is supported with a memory circuit for storing the digital weights and a memory lookup table or possibly a multiplexer circuit for weighting of the difference signal. An analog embodiment uses a plurality of comparators responsive to the input signal vector and the weight signals for providing the output signal of the neuron as the absolute value of the difference of the input signal vectors and the weight signals.
