How do we version and manage model weights?

Managing weight versions is key to reproducibility.
Samy Bengio

How It Works:

Use artifact stores (like S3 or MLflow) to tag weight files with metadata (training data, hyperparameters) and link them to model IDs in your registry.

Key Benefits:

  • Traceability: Know exactly which weights produced which results.
  • Rollbacks: Revert to prior weight versions instantly.
  • Collaboration: Teams share and reproduce experiments.

Real-World Use Cases:

  • A/B testing: Compare performance of weight versions in production.
  • Compliance: Archive weights for audit trails.
