PROFILE
Leon Dong
Leon enhanced the facebookresearch/detectron2 repository by developing and refining data processing and evaluation pipelines for the Vizard Framework, focusing on scalable handling of large datasets and robust model evaluation. Using Python and leveraging skills in computer vision and machine learning, Leon introduced new test configurations, improved rotated box support, and streamlined evaluation workflows by implementing an evaluation callback aligned with d2go standards. He also addressed configuration risks by refactoring evaluator components and restoring test stability through targeted bug fixes. The work demonstrated depth in both feature development and maintenance, resulting in more reliable, maintainable, and production-ready evaluation processes.

Nov 1, 2024November 2024: Delivered evaluation workflow enhancements for the Detectron2 repo, focusing on reliable evaluation timing, reduced configuration risk, and maintainability. Key changes include addition of an Eval Callback to replace native Vizard evaluation, with evaluation now triggered at the end of cfg.TEST.EVAL_PERIOD train steps to align with the d2go evaluator and ensure consistent timing for users. Also performed a refactor of the Evaluator Builder to remove an unused parameter, reducing potential errors and streamlining configuration for RotatedCocoEvaluator. These changes improve evaluation reliability, reduce user friction during onboarding, and support more robust rotated detector workflows.
