Noise and the performances of the metrics. Here, the amount of input from the Poisson background is varied: h is plotted against the relative value of the synaptic strengths g and gP for the new and ARMV metrics. For each value of gP /g, the synaptic strengths were tuned to give the LIF neurons a firing rate of 20 Hz. Because the background spiking has a higher average rate, gP /g = 1 corresponds to an input where the background component is, on average, 2.5 times larger than the component coming from the receptive neurons.
