class norse.torch.functional.lif_ex.LIFExParameters(delta_T: Tensor = tensor(0.5000), tau_syn_inv: Tensor = tensor(200.), tau_mem_inv: Tensor = tensor(100.), v_leak: Tensor = tensor(0.), v_th: Tensor = tensor(1.), v_reset: Tensor = tensor(0.), method: str = 'super', alpha: float = 100.0)

Parametrization of an Exponential Leaky Integrate and Fire neuron

Parameters:

delta_T (torch.Tensor): sharpness or speed of the exponential growth in mV 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
