Han Xie contributed to the awslabs/graphstorm repository by developing three core features over three months, focusing on enhancing model evaluation and training workflows for graph neural networks. He implemented RGAT edge feature support, introducing new modules and end-to-end tests to validate edge-feature configurations across multiple tasks. Han also expanded binary classification capabilities by adding precision_at_recall and recall_at_precision metrics, updating evaluation functions, configuration, and documentation. Additionally, he enabled fixed-test-size configuration for link prediction training, improving reproducibility and benchmarking. His work demonstrated depth in Python, PyTorch, and configuration management, with a strong emphasis on robust testing and reliable model assessment.

July 2025: Implemented a fixed-test-size configuration for Link Prediction (LP) training in the LM framework within awslabs/graphstorm. This feature passes the fixed-test-size parameter to dataloader classes to enable controlled evaluation, accompanied by a dedicated test case verifying functionality with a specific dataset and configuration. These changes improve evaluation reproducibility, benchmarking consistency, and overall model selection reliability.
