Abstract:
1. A learning method of a neural network circuit including a plurality of neural network circuit elements which are interconnected, wherein each of the plurality of neural network circuit elements includes: wherein the synapse circuit includes a variable resistance element which includes: wherein the synapse circuit is configured to perform switching between a state in which the first input signal is permitted to be input to the first electrode of the variable resistance element, and a state in which the first input signal is inhibited from being input to the first electrode, wherein the neuron circuit includes a waveform generating circuit for generating a bipolar sawtooth pulse voltage, wherein the method comprises: wherein the resistance value of the variable resistance element changes due to an electric potential difference between the first electrode and the control electrode, the electric potential difference being generated depending on an input timing difference between a voltage applied to the first electrode and the voltage applied to the control electrode.
