hxtorch.spiking.modules.input_neuron.InputNeuron

class hxtorch.spiking.modules.input_neuron.InputNeuron(*args, **kwargs)

Bases: hxtorch.spiking.modules.types.population.InputPopulation

Spike source generating spikes at the times given in the dense spike_times array binned with the time step of the experiment.

__init__(*args, **kwargs)

Initialize internal Module state, shared by both nn.Module and ScriptModule.

Methods

__init__(*args, **kwargs)	Initialize internal Module state, shared by both nn.Module and ScriptModule.
forward_func(input[, hw_data])
get_spike_times()
post_process(hw_data, runtime)	This methods needs to be overridden for every derived module that demands hardware observables and is intended to translated hardware- affine datatypes returned by grenade into PyTorch tensors.

post_process(hw_data: HXTorchObservables, runtime: float) → Tuple[Optional[torch.Tensor], …]

This methods needs to be overridden for every derived module that demands hardware observables and is intended to translated hardware- affine datatypes returned by grenade into PyTorch tensors.

Parameters

• hw_data – A HardwareObservables instance holding the hardware data assigned to this module.

• runtime – The requested runtime of the experiment on hardware in us.

• dt – The expected temporal resolution in hxtorch.

Returns

Hardware data represented as torch.Tensors. Note that torch.Tensors are required here to enable gradient flow.
