KI-Modellüberwachung

Establish a baseline from a documented period and model version. Track missing fields, invalid ranges, new categories, latency, and output distributions. These signals can detect pipeline failures before enough outcome labels are available to assess predictive quality. When reliable outcomes arrive, compare performance with the original evaluation and with relevant recent periods. Report subgroup results and sample sizes. Delayed or selectively collected labels can make a dashboard look more complete than its evidence supports. Distinguish data drift from changes in the relationship between inputs and outcomes. A seasonal shift may be expected, while a changed feature definition may indicate a software defect. Investigate the cause before choosing retraining as the response. Define alert thresholds, review responsibility, and a recovery decision. Responses can include correcting data, rolling back a release, changing a threshold, or retraining. Verify the intervention on appropriate evaluation material and continue measuring afterward. Monitoring should lead to informed action rather than automatic model churn.
