Your question is Monitor and Improve Model Performance. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You are responsible for a model that is already in production, and the team wants a clear way to watch its performance over time. The main concern is knowing when the model is drifting, when the threshold is no longer right, and when a retrain or rollback is needed.
How would you monitor model performance and implement improvements as necessary?
