N-BIT PARITY NEURAL NETWORK ENCODING DEVICE

摘要

PURPOSE:To greatly decrease the number of neuron cells which constitute a hidden layer. CONSTITUTION:A three-layered artificial neural network 50 which has N input terminals, the hidden layer of 1st and 2nd neuron cells 54 and 56, and an output layer of a single neuron cell 52 generates an output parity signal indicating whether or not the number of bits displayed at the N-bit input terminals is even or odd. The bits of the neuron cells 54 and 56 of the hidden layer have an active function for deriving a derivative as to linear response characteristics which can separate the mean weighted sum of input bits into an odd and an even group.
