Can YOLO support incremental training to add new data or classes without starting from scratch?

Hi,
I’m working with YOLO models and want to know whether they support incremental training for new classes.

Is it possible to add additional object classes to an already trained model without retraining from scratch or rebuilding the entire dataset?
If so, what is the recommended workflow to avoid issues like catastrophic forgetting?

Thanks in advance!

No. You can’t avoid catastrophic forgetting without very specialized training techniques.
