Many models perform well during training and validation but start degrading in production due to data drift, concept drift, or changing user behavior. What monitoring strategies, retraining pipelines, or evaluation practices do you use to maintain model performance in production environments?

Model performance degradation after deployment is usually caused by data drift, concept drift, or changes in user behavior. Handling it requires both monitoring and a clear retraining strategy.

A few practices that work well in production:

Continuous monitoring: Track model metrics such as accuracy, precision, or prediction distribution and compare them with training benchmarks.
Drift detection: Monitor input feature distributions and target distributions to detect data or concept drift early.
Retraining pipelines: Set up automated or scheduled retraining using fresh data when performance drops below a defined threshold.
Human review loops: For critical systems, periodically review predictions to identify failure patterns that metrics alone may miss.

In practice, the key is treating models as living systems that require ongoing monitoring, evaluation, and iteration, rather than one-time deployments.
