Cloud-Native AI Monitoring Service Offers Scalable Evaluation with Guarantees.

Summary

Researchers introduce EaaS, a cloud-native microservices architecture for scalable AI monitoring, operationalizing evaluation methods like conformal prediction, calibration, drift detection, and fairness monitoring. It validates key methodological concerns, demonstrating consistent empirical coverage and effective drift detection.

A new cloud-native reference architecture, Evaluation-as-a-Service (EaaS), has been developed to provide scalable and robust AI monitoring. This system is built on six stateless Kubernetes microservices, integrating advanced evaluation techniques such as conformal prediction for uncertainty quantification, calibration assessment, drift detection using RFF-approximated Maximum Mean Discrepancy, and fairness monitoring with bootstrap confidence intervals. The architecture also includes a DAG-based orchestrator and a result storage API. The EaaS framework has been rigorously validated across several key methodological areas. It demonstrated consistent empirical coverage aligned with marginal conformal guarantees, effective drift detection for both mild and severe changes, and identified significant demographic parity disparities in fairness monitoring. The system also achieves low latency for critical services like conformal prediction and calibration, making it suitable for real-time applications, while other services like drift detection are designed for periodic batch monitoring.

Why it matters

Professionals building and deploying AI systems need robust, scalable, and reliable methods to monitor model performance, fairness, and drift in production. This architecture offers a structured approach to operationalize advanced AI evaluation techniques, ensuring models remain trustworthy and performant over time.
