What problem does it solve? Building a production ML system involves far more than training a model — teams struggle with experiment tracking, reproducibility, deployment, and detecting performance degradation in production. This Skill provides a complete blueprint for designing an ML pipeline from raw data to monitored production deployment. ## Core Features & Use Cases - Full Pipeline Design: Covers data extraction, feature engineering, time-based train/val/test splits, training with MLflow experiment tracking, evaluation, deployment, and monitoring. - Production Deployment Patterns: Includes model registry promotion, FastAPI serving with health checks, Docker packaging, and Kubernetes deployment guidance. - Monitoring & Retraining: Implements drift detection with Evidently, Prometheus metrics, and Airflow-triggered automated retraining on performance degradation. - Use Case: A data science team building a churn prediction system can follow this Skill to set up XGBoost training with MLflow tracking, deploy a real-time prediction API, and automatically retrain when AUC drops more than 10% from baseline. ## Quick Start Ask the AI to design an end-to-end ML pipeline for your use case, specifying the problem type, data sources, and deployment requirements.
