fann_get_activation_function Returns the activation function &reftitle.description; intfann_get_activation_function resourceann intlayer intneuron 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. &reftitle.parameters; ann &fann.ann.description; layer Layer number. neuron Neuron number. &reftitle.returnvalues; Learning functions constant or -1 if the neuron is not defined in the neural network, or &false; on error. &reftitle.seealso; fann_set_activation_function_layer fann_set_activation_function_hidden fann_set_activation_function_output fann_set_activation_steepness fann_set_activation_function
