Chronix Model Lifecycle Management

Provides model registry, versioning, champion/challenger A/B testing, drift detection, and accuracy tracking for forecast and anomaly models.

Components

• ModelRegistry — versioned storage with champion/challenger tagging
• ABTest — champion/challenger A/B evaluation
• DriftDetector — distribution drift detection (PSI, KS, ADWIN)
• Adwin — streaming ADWIN change detection (Bifet & Gavaldà 2007)
• AccuracyTracker — sliding-window accuracy metrics and staleness
