norse.torch.functional.lif_current_encoder

norse.torch.functional.lif_current_encoder(input_current: Tensor, voltage: Tensor, p: LIFParameters, dt: float = 0.001) → Tuple[Tensor, Tensor]

Computes a single euler-integration step of a leaky integrator. More specifically it implements one integration step of the following ODE

\[\begin{split}\begin{align*} \dot{v} &= 1/\tau_{\text{mem}} (v_{\text{leak}} - v + i) \\ \dot{i} &= -1/\tau_{\text{syn}} i \end{align*}\end{split}\]

Parameters:

input (torch.Tensor): the input current at the current time step voltage (torch.Tensor): current state of the LIF neuron p (LIFParameters): parameters of a leaky integrate and fire neuron dt (float): Integration timestep to use
