Set the activation function for neuron number neuron in layer number layer, counting the input layer as layer 0.
It is not possible to set activation functions for the neurons in the input layer.
When choosing an activation function it is important to note that the activation functions have different range. FANN_SIGMOID
is e.g. in the 0 - 1 range while FANN_SIGMOID_SYMMETRIC
is in the -1 - 1 range and FANN_LINEAR
is unbound.
The supplied activation_function value must be one of the activation functions constants.
The return value is one of the activation functions constants.
Neural network resource.
The activation functions constant.
Layer number.
Neuron number.
Returns TRUE
on success, or FALSE
otherwise.
