(A) Schematic of the LSM and the given task. Spike sources are composed of 50 ms segments drawn from two template spike trains (X and Y). These patterns are streamed into the liquid (with descending index), which is a network consisting of 191 neurons, leaving one neuron for the tempotron. Connection probabilities are depicted next to each connection (arrows). In two experiments, the tempotron is trained to either classify the origin (X or Y) of the spike train segment with index 1 or 2. (B) The classification performance of the LSM measured over 200 samples after 1000 training iterations for both hardware (lighter) and software (darker) implementation.
