Answer
- B Regularly evaluating the operational model against its acceptance criteria to identify drift
- C If necessary, training a new model and comparing it with the existing one, for example using A/B testing
Explanation
During operation, the model's situation may evolve and it may drift away from its intended performance. The model is therefore regularly evaluated against its acceptance criteria. If needed, it is retrained with new data and/or hyperparameters, and the new model is compared with the existing one using a form of A/B testing.
