Version control is crucial in machine learning (ML) due to the complexity of its development process, which involves managing vast amounts of data, testing multiple models, optimizing parameters, and tuning features. It enables the tracking and management of changes in code, data, and model parameters to ensure reproducibility, collaboration, and efficient experimentation. There are two main types of version control systems: Distributed, where each developer has a full copy of the codebase locally, and Centralized, where a single server holds the repository. Proper version control in ML involves creating separate repositories and branches for different model parameters and features, allowing for thorough evaluation and validation of each change. Tools like neptune.ai, DVC, and ML Metadata offer specialized solutions for tracking experiments and maintaining consistency across ML projects. These tools facilitate collaboration, enhance reproducibility, and streamline the development process by providing clear insights into data and model changes, ultimately aiding in maintaining stable and efficient model training and deployment.
