Key Points

  • The article explains how deployed machine learning models can degrade over time due to model drift, undermining reliability and user trust.
  • It outlines common ways drift can occur in production, including changes in data distributions and evolving real-world conditions.
  • It describes practical approaches to detect drift early through monitoring and validation during ongoing operation.
  • The post provides guidance on how to respond to detected drift, such as retraining, updating pipelines, and revising model or feature handling strategies.

How production models fail over time, and how to catch and fix it before it breaks trust.
