Input-output sequences in STDP-tempotron: (reproduced from Iyer and Chua, 2020, Figure 1). (A) Sequence of frames created from input spikes. Input spikes collapsed over every m ms, where m is $\frac{1}{10}th$ the presentation time. The images from top to bottom depict a pattern from the class right hand clockwise. (B) The images from top to bottom show the sequence of output neurons that spike in response to the input. Each output neuron is represented by weights from the input, and rearranged on a 128 × 128 grid as in Figure 5. As can be seen, the sequence of output neurons that fire on the right, look very similar to the input spikes on the left.
