fann_get_learning_momentum — Returns the learning momentum
$ann
   )
   The learning momentum can be used to speed up FANN_TRAIN_INCREMENTAL training.
   A too high momentum will however not benefit training. Setting momentum to 0 will be the same as
   not using the momentum parameter. The recommended value of this parameter is between 0.0 and 1.0.
  
The default momentum is 0.
