 to add person into the group, and call [LargePersonGroup -

 'recognitionModel' should be specified to associate with this large person
 group. The default value for 'recognitionModel' is 'recognition_01', if the
 latest model needed, please explicitly specify the model you need in this
 parameter. New faces that are added to an existing large person group will
 use the recognition model that's already associated with the collection.
 Existing face features in a large person group can't be updated to features
 extracted by another version of recognition model.
