Parametrization of a LIF neuron

Parameters:
tau_syn_inv (torch.Tensor): inverse synaptic time

constant (\(1/\tau_\text{syn}\)) in 1/ms

tau_mem_inv (torch.Tensor): inverse membrane time

constant (\(1/\tau_\text{mem}\)) in 1/ms

v_leak (torch.Tensor): leak potential in mV v_th (torch.Tensor): threshold potential in mV v_reset (torch.Tensor): reset potential in mV method (str): method to determine the spike threshold

(relevant for surrogate gradients)

alpha (float): hyper parameter to use in surrogate gradient computation
