Model Versioning
Domain: MLOps
🎯 Motivation
Tracking model versions over time. Each retrain creates a new version with updated performance.
📋 Concrete Example
Versioning: v1 (Jan, 88%), v2 (Mar, 91%), v3 (Jun, 93%). If v3 has a bug, rollback to v2. Versioning enables safe updates and rollbacks.
🔗 Analogy
Software updates on your phone - iOS 17.1, 17.2, 17.3. Each version is tracked. If 17.3 has a bug, you can downgrade. Model versioning works the same way.
