Spike-Based Approximate Backpropagation Algorithm of Brain-Inspired Deep SNN for Sonar Target Classification

<div>A simple example of the coding process. A 4 × 4 pixel image block is selected from the image, and the last column of the image block is transformed into the spike trains with a time step of 10, conforming to the Poisson distribution according to the pixel intensity.</div>
