🎓 Research Interests

My research interests center on Data-centric Machine Learning (DCML), including Graph Machine Learning and Data-empowered AI.

• Graph Machine Learning: Currently, graph neural networks have continued to adopt Transformer or message passing architectures, with performance gains shifting from model improvements to data improvements. My primary focus is on obtaining large quantities of high-quality data at lower costs and in shorter timeframes, by approaching from the perspectives of graph quality, quantity, and efficiency. The main research areas are: heterogeneous graph neural networks, self-supervised graph learning, federated graph learning, graph condensation, and graph foundation models.

• Data-empowered AI: As the limitations of graph data gradually become apparent, this research theme will transition from the study of graph data to the study of general data, by introducing graph concepts to enhance the collaborative efficiency between models, modules, or agents. Through graphs, LLMs or agents can be explicitly associated, further unleashing their expressive capabilities. The main research areas are: data valuation, data distillation, LLM quantization, and agentic AI.

🎯 More importantly, I am collaborating with my long-term partner Xiangkai Zhu on a conceptual studys for GCML. This encompasses more diverse domain datasets, wider range of evaluation metrics, more comprehensive surveys, more systematic benchmarks, and deeper insights. This study will be published shortly.
