How to monitor and when to retrain the object detection model in production?

@ptrblck , I recently moved regression model to production and I’m monitoring the model drift and data drift using statistical tests, based on their distributions i retrain the model.

Could you please tell me how to monitoring the object detection model and detect drifts ?

Do you use statistical test to detect drifts? If yes, how do you do that? And which value you as an input to detect?

Please guide me? Even if you could provide any relevant article also would help me

Thanks in advance😊
