fann_get_activation_function

(PECL fann >= 1.0.0)

fann_get_activation_function — Returns the activation function

fann_get_activation_function(resource $ann, int $layer, int $neuron): int

Get 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.

Learning functions constant or -1 if the neuron is not defined in the neural network, or false on error.

fann_set_activation_function_layer() - Sets the activation function for all the neurons in the supplied layer
fann_set_activation_function_hidden() - Sets the activation function for all of the hidden layers
fann_set_activation_function_output() - Sets the activation function for the output layer
fann_set_activation_steepness() - Sets the activation steepness for supplied neuron and layer number
fann_set_activation_function() - Sets the activation function for supplied neuron and layer
