What problem does it solve? Managing machine learning models in production requires versioning, monitoring, drift detection, and retraining infrastructure that teams often build ad hoc. This Skill provides concrete implementation patterns for the full ML lifecycle from deployment to automated retraining. ## Core Features & Use Cases - Model Registry & Serving: Register versioned models with metadata and serve them through a FastAPI prediction endpoint with health checks. - Monitoring & Drift Detection: Track latency, error rates, and accuracy in production, and detect data drift using Kolmogorov-Smirnov tests and Population Stability Index. - Experiment Tracking & Retraining: Log training runs with MLflow and trigger automated retraining when performance drops or drift is detected. - Use Case: A team deploying a churn prediction model can register each version, serve predictions via API, monitor accuracy against live labels, and automatically retrain when feature distributions drift. ## Quick Start Set up a model registry and FastAPI serving endpoint for my trained classifier with drift monitoring and automated retraining triggers.
