How model versioning is different from software versioning?

Model versioning tracks code, data, hyperparameters, model architecture, and training environments, ensuring reproducibility and comprehensive performance metrics. Unlike regular software versioning, it accommodates frequent iterations and varied datasets. This approach brings benefits such as enhanced collaboration, precise performance comparison, and the ability to quickly revert to previous versions, ensuring reliable and high-quality models.

Systematic tracking and management

Implementing version control systems ensures systematic tracking and management of model versions, allowing for organized documentation and retrieval of specific versions.

Reproducibility and consistency

By maintaining detailed records of data, hyperparameters, and code, model versioning ensures that each version can be reproduced accurately, maintaining consistency across experiments and deployments.

Enhanced collaboration

Model versioning supports collaboration by providing a clear history of model iterations, facilitating communication and coordination among team members working on different versions.

Rollback and comparison

The ability to easily roll back to previous model versions and compare performance metrics enables quick resolution of issues and informed decision-making, ensuring stable and reliable model performance.

In highly regulated industries like pharma, proper model versioning is essential. While software versioning is straightforward, incorporating data adds significant complexity. It requires tracking the entire model's development path, including experimentation history and data used throughout the process. However, once implemented, it provides excellent value by ensuring compliance, improving auditability and model management. It also opens door for further analysis of your model development performance.
