Evaluation Metrics and Production Safety Questions

Design evaluation metrics and safety guardrails that reflect downstream business impact and user experience. Choose appropriate statistical metrics such as precision, recall, F one score, and area under curve as well as cost weighted objectives, and translate model outputs to business level metrics such as cancellation rates or revenue impact. Define guardrail metrics to detect regressions or harms, discuss threshold selection and calibration, and explain how to monitor and respond to metric signals in production including shadow testing and human in the loop checks.
