🔬 研究领域：关系智能 (Relational Intelligence)
关系智能是理解和建模复杂系统中多层次关系结构的科学范式，涵盖以下四个层次：
📂 研究项目
1. 知识增强的语言模型
- 上下文知识：检索增强（RAG）
- 参数知识：知识编辑（Knowledge Editing）
- 个性化：模型个性化（Personalization）
2. 拓扑感知的数据模型
- 建模：图数据合成（Data Generation）
- 预测：图表征学习（Representation Learning）
- 仿真：多智能体交互（Multi-agent Collaboration）
- 计算：图基础模型（Foundation Model）
