Equivalence of approximation by networks of single- and multi-spike neurons

ArXi:2603.13478v1 Announce Type: cross In a spiking neural network, is it enough for each neuron to spike at most once? In recent work, approximation bounds for spiking neural networks have been derived, quantifying how well they can fit target functions. However, these results are only valid for neurons that spike at most once, which is commonly thought to be a strong limitation.
