In January 2025, Michael Gao developed new Absolute Error and Mean Absolute Error metrics for the voxel51/fiftyone-plugins repository, enabling per-sample and per-frame evaluation within data-centric machine learning workflows. He refactored metric classes in Python to improve robustness and maintainability, aligning regression tagging and introducing lower_is_better semantics for consistent metric behavior. Michael enhanced the API by moving get_fields and adding compute_by_sample, supporting more granular analytics and easier integration. His work consolidated related commits for better traceability, resulting in a cleaner contribution history. These changes improved the precision of evaluation and streamlined debugging for plugin-based machine learning pipelines.
