Figure 12. The dependence of chronotron performance on the firing rate of the inputs.

The inputs were generated using a Gamma process having a normalized average period (the average period over the trial length) (Methods). (A) The maximum load (the capacity ) as a function of the normalized average period . (B) The number of learning epochs required for correct learning as a function of the normalized average period , for various loads . (C) The number of learning epochs required for correct learning as a function of load , for various values of the normalized average period . Best capacity was achieved for values of around 1, i.e. a single input spike per trial, for each synapse, on average, while fastest learning was achieved for around 0.5.
