Online Shift Detection and Conformal Adaptation for Deployed Safety Classifiers

arXiv:2606.11949v1 Announce Type: new Abstract: We present an online monitoring system for distributional shift in deployed safety classifiers, using calibrated sequential statistics to detect when a classifier has moved out of distribution. Upon detection, a conformal abstention layer adapts decision thresholds to recover a target error rate epsilon=0.1. In a pre-registered factorial evaluation (4 classifiers x 5 shift conditions x 20 seeds x 2 window sizes, 800 cells), the system achieves 86.6% valid detection (693/800, 95% CI [84.1%, 88.8%]) with mean latency of 39.5 steps. Detection holds

Why this matters
Why now

The increasing deployment of AI into critical 'safety-critical' systems necessitates robust monitoring and adaptation mechanisms to maintain performance and trust.

Why it’s important

Ensuring the reliability and safety of deployed AI systems is crucial for their adoption across various industries, impacting regulatory frameworks and public acceptance.

What changes

AI systems can now be continuously monitored for performance degradation due to distributional shifts and automatically adapt, reducing the need for manual oversight and intervention.
