What is ML Code Review Process?

Implement comprehensive monitoring, automated testing, version control, incident response procedures, and continuous improvement processes aligned with organizational objectives.

ML code reviews should add five domain-specific checks: data handling correctness (train-test split leakage, feature engineering applied consistently across training and serving), experiment validity (random seed setting, appropriate metric selection, statistical significance of claimed improvements), model-specific antipatterns (hardcoded thresholds, undocumented assumptions about data distributions, magic numbers without explanation), reproducibility (all dependencies pinned, data sources versioned, configuration externalized), and production readiness (error handling for missing features, graceful degradation paths, monitoring instrumentation). Create a checklist template in your PR template covering these categories alongside standard code quality items.

Structure reviews so non-ML engineers can provide valuable feedback: separate data processing code (reviewable by any engineer) from model architecture code (requires ML expertise), require inline documentation explaining why specific hyperparameters or architectures were chosen, use automated linting tools (pylint, mypy, black) to handle style consistency so reviewers focus on logic, and create decision logs explaining model choices with alternatives considered. Pair junior ML practitioners with senior engineers for cross-domain learning during reviews. For critical model changes, require two approvals: one from an ML specialist on methodology and one from a software engineer on production readiness.
