Encodes an input value by the time the first spike occurs. Similar to the ConstantCurrentLIFEncoder, but the LIF can be thought to have an infinite refractory period.


input_current (torch.Tensor): Input current to encode (needs to be positive). sequence_length (int): Number of time steps in the resulting spike train. p (LIFParameters): Parameters of the LIF neuron model. dt (float): Integration time step (should coincide with the integration time step used in the model)
