METHOD FOR OPERATING NEURAL NETWORK

This abstract first appeared for US patent application 18334271 titled 'METHOD FOR OPERATING NEURAL NETWORK

Original Abstract Submitted

A method is provided and includes operations as below: receiving an input in an input layer of a spiking neural network during time steps, wherein the input includes multiple spikes; generating, based on multiple activation values corresponding to the spikes, location information including count numbers each corresponding to non-zero values, in the activation values, in one of multiple rows of the input; performing, based on the location information, a matrix multiplication with the non-zero values in a first number of rows in the rows with a first group of filters of weight values to generate multiple first membrane potentials for outputting a first output spike; and performing, based on the location information, the matrix multiplication with the non-zero values in a second number of rows in the rows with the first group of filters of weight values to generate multiple second membrane potentials for outputting a second output spike.
