A Comprehensive Guide on How to Monitor Your Models in Production

Deploying machine learning models to production is not the final step in their lifecycle, as they require continuous monitoring to ensure optimal performance and business value. This comprehensive guide outlines the necessity of post-deployment monitoring, emphasizing the dynamic nature of models that degrade over time due to real-world changes. The guide identifies key challenges such as data distribution changes, model drift, and adversarial attacks, and provides solutions like statistical checks and shared model ownership. It discusses both functional and operational monitoring, covering aspects like data quality, feature drift, and system performance metrics. The importance of logging and setting up actionable alerts is highlighted for effective troubleshooting and compliance. The guide also advises on selecting suitable monitoring platforms based on the organization's MLOps maturity level, ensuring that model deployment continues to deliver positive business value.
