Yan contributed to the adap/flower repository by delivering a refreshed federated learning starter kit and modernizing FlowerTune examples. Using Python and PyTorch, Yan updated XGBoost federated templates to integrate the FedXgbBagging strategy, refined configuration management, and improved data handling for smoother onboarding. The work included refactoring general templates and tabular examples, updating dependencies, and enhancing code clarity for maintainability. Yan also strengthened documentation with detailed upgrade guides and tutorials, and addressed robustness in federated learning strategies by fixing FedAvg evaluation logic. The depth of these changes improved both developer experience and the reliability of federated machine learning workflows.

September 2025 delivered a refreshed federated learning starter kit in adap/flower, modernized FlowerTune examples, and strengthened documentation and reliability. Key features include XGBoost Federated Quick-Start Templates aligned with the latest Flower API and FedXgbBagging integration; modernization of FlowerTune-LLM/ViT examples; comprehensive general template/tabular/baseline updates; enhanced upgrade guides and tutorials; and robustness fixes to FedAvg evaluation logic to gracefully handle zero-fraction training/evaluation.
