(PECL fann >= 1.0.0)
Returns the cascade activation functions
array fann_get_cascade_activation_functions ( resource $ann )
The cascade activation functions array is an array of the different activation functions used by the candidates
See fann_get_cascade_num_candidates() for a description of which candidate neurons will be generated by this array.
The default activation functions are FANN_SIGMOID
, FANN_SIGMOID_SYMMETRIC
, FANN_GAUSSIAN
, FANN_GAUSSIAN_SYMMETRIC
, FANN_ELLIOT
, FANN_ELLIOT_SYMMETRIC
