Title:
IMPROVED SPIKING NEURAL NETWORK APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/018231
Kind Code:
A3
Abstract:
A spiking neural network is described that comprises a plurality of neurons in a first layer connected to at least one neuron in a second layer, each neuron in the first layer being connected to the at least one neuron in the second layer via a respective variable delay path. The at least one neuron in the second layer comprises one or more logic components configured to generate an output signal in dependence upon signals received along the variable delay paths from the plurality of neurons in the first layer. A timing component is configured to determine a timing value in response to receiving the output signal from the one or more logic components, and an accumulate component is configured to accumulate a value based timing values from the timing component. A neuron fires in a case that a value accumulated at the accumulate component reaches a threshold value.
