Rate-independent RIA-SPIKE-distance vs. A-SPIKE-distance and A-ISI-distance for Poisson (A) and steady-rate spike trains (B). (A) Distances for two Poisson spike trains with varying rate ratios. The overall number of spikes in the two spike trains is kept constant. Each data point is an average over 100 trials. In contrast to the clearly rate-dependent A-ISI- and A-SPIKE-distances, the rate-independent RIA-SPIKE-distance exhibits an almost constant curve. (B) For the steady-rate spike train curves each data point is an average over 100 trials with random phase shifts between the two spike trains. In this case the line for the RIA-SPIKE-distance is indeed perfectly constant.
