Neural network device and signal processing method

Abstract

Minimize the loss of information transmitted. [Solution] The neural network device comprises a plurality of synaptic circuits and a plurality of neuron circuits. Each of the plurality of synaptic circuits acquires one or more spike signals output from any one of the plurality of neuron circuits, and when it acquires one or more spike signals, it outputs a synaptic current of a set amount corresponding to the set synaptic weight and the one or more spike signals. The first neuron circuit outputs N spike signals as one or more spike signals. The first neuron circuit has a spike output circuit that outputs at least the nth spike signal among the N spike signals when the membrane potential is greater than the nth threshold potential among N different threshold potentials.
