Before revision:  While we consider the leaky integrate-and-fire neuron model in this work, our methodology to derive the gradient can be applied to other spiking neuron models . As errors are backpropagated in an event-based manner (at spike times), EventProp requires the storage of state variables only at these times, providing favorable memory requirements .
