Machine learning models degrade with time. You need to update and retrain them regularly. However, the decision on the maintenance approach is often arbitrary, and the models are simply retrained on a schedule or after every new batch. This can lead to suboptimal performance or wasted resources. In this talk, I will discuss how we can do better: from estimating the speed of the model decay in advance to constructing a proper evaluation set.
