% Learning the XOR Function.
% --------------------------
main:-

   % More economical would be:
   % fann_create_standard( [2, 3, 1], Ann ),

   nl,
   fann_print_connections( Ann ),
   nl,
   fann_print_parameters( Ann ),
   nl,

   fann_set_activation_function_hidden( Ann, 'FANN_SIGMOID_SYMMETRIC' ),
   fann_set_activation_function_output( Ann, 'FANN_SIGMOID_SYMMETRIC' ),

   % Insert the proper paths below

   fann_train_on_file( Ann, "xor.data", 500000, 1000, 0.00001 ),
   nl,
   fann_save( Ann, "xor_float.net" ),
   fann_destroy( Ann ).
