fann_type fann_get_activation_output_steepness(struct fann * ann);
Return the steepness of the activation function of the output layer.
The steepness defaults to 0.5 and a larger steepness will make the slope of the activation function more steep, while a smaller steepness will make the slope less steep. A large steepness is well suited for classification problems while a small steepness is well suited for function approximation.
This function is deprecated and will be removed in a future version. Use
fann_get_activation_steepness_output instead.
This function appears in FANN >= 1.0.0. and is deprecated in FANN >= 1.2.0.
