Key concepts covered include survival functions, hazard functions, the Weibull distribution (with shape parameter β and scale parameter η), and how data drift accelerates model failure. The post demonstrates drift-adjusted Weibull simulations for modeling time-to-failure, applies Kaplan-Meier and Nelson-Aalen estimators to both a simulated ML reliability dataset and a real Veterans' lung cancer clinical dataset, and shows how hazard-based insights help identify when models begin degrading. The framework enables principled retraining schedules and monitoring policies rather than ad hoc thresholds. ## Full article daily.dev links to this article rather than hosting it.
