Flashcard Practice Chartered AI Engineering Professional - CAiEP Multiple Choice

A retailer launches a new subscription program, and a recommender's historical loyalty-tier features no longer represent customer behavior well. What is the best feature-engineering response?

Choose the Best Answer

Remove all customer-history features so the model depends on product popularity. Freeze the old loyalty features because changing inputs makes comparisons harder. Monitor drift, design subscription-aware features, and validate rollout. Change the model registry description while keeping existing feature definitions.
