[docs]class FullyConnected(Layer): """This is used for most processing purposes, since any neuron in the layer can be connected to any input channel. Outputs are returned from FullyConnected layers as a list of events, that is, as a triplet of x, y and feature values. However, FullyConnected models by definition have no intrinsic spatial organization. Thus, all output events have x and y values of zero with only the f value being meaningful – corresponding to the index of the event-generating neuron. Note that each neuron can only generate a single event for each packet of inputs processed. Args: units (int): number of units. name (str, optional): name of the layer. weights_bits (int, optional): number of bits used to quantize weights. activation (bool, optional): enable or disable activation function. threshold (int, optional): threshold for neurons to fire or generate an event. act_step (float, optional): length of the potential quantization intervals. act_bits (int, optional): number of bits used to quantize the neuron response.
