Drift detectors in ML monitoring prone to false alarms, study finds

A new research paper analyzes the false alarm rates of common drift detection methods used in machine learning monitoring. The study found that while PSI is sensitive to batch size and can produce frequent false alarms with small sample sizes, its performance improves with batches over 200 samples. KS, MMD, and LSDD showed more consistent but still fluctuating reliability across batch sizes. Applying a Bonferroni correction reduced false positives but also decreased true positive sensitivity, highlighting the inherent trade-off between stability and sensitivity in drift detection. AI

IMPACT Highlights potential issues with common ML monitoring tools, suggesting careful calibration is needed for production systems.
