In November 2025, Han Feng contributed to the scikit-learn-contrib/MAPIE repository by enhancing the robustness of BlockBootstrap cross-validation, ensuring all non-training samples are included in test sets and that incomplete blocks use the last available samples. This update, implemented in Python, improved the reliability of model evaluation and included comprehensive test revisions to prevent regressions. Han also upgraded development tooling by adding Ruff for code quality assurance and updated project documentation and contributor records using reStructuredText. These contributions demonstrated depth in dependency management, documentation, and machine learning workflows, supporting both maintainability and collaborative development within the MAPIE project.
November 2025 MAPIE contributions focused on robustness, quality, and documentation to support reliable model evaluation and scalable collaboration. Delivered a BlockBootstrap cross-validation fix that ensures test sets include all non-training samples and uses the last samples when blocks are incomplete, with tests updated to prevent regressions. Updated project documentation and contributor records to reflect recent contributions. Upgraded development tooling by adding Ruff to dev dependencies to improve code quality checks during development. These changes enhance evaluation reliability, developer productivity, and project maintainability, aligning with our goals of robust ML validation and efficient collaboration.
