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

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

$$\begin{array}{r}\begin{array}{rl}\dot{v}& =1/{\tau }_{\text{mem}}(v_{\text{leak}}-v+i)\\ \dot{i}& =-1/{\tau }_{\text{syn}}i\end{array}\end{array}$$

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
