$ann
, int $layer
, int $neuron
) : intGet the activation function for neuron number neuron in layer number layer, counting the input layer as layer 0.
It is not possible to get activation functions for the neurons in the input layer.
The return value is one of the activation functions constants.
annNeural network resource.
layerLayer number.
neuronNeuron number.
Learning functions constant or -1
if the neuron is not defined in the neural network, or FALSE on error.
