韦淳于，博士，中国人民大学信息学院讲师，中国人民大学国家治理大数据和人工智能创新平台研究员。2019年于清华大学自动化系，获学士学位。2024年于清华大学自动化系，获博士学位。在博士期间,我以第一作者发表高水平论文十三篇，研究成果在腾讯，阿里和快手等公司落地。
研究方向为图机器学习和知识增强大模型，具体包括:
- 面向复杂人机系统的多模态图数据的建模、预测、仿真、计算：
- 建模：图数据合成（Graph Generation）
- 预测：图表征学习（Graph Representation Learning）
- 仿真：图约束的多智能体交互 （Graph Learning for Multi-agent Collaboration）
- 计算：拓扑感知的大语言模型 （Graph-aware LLM）
- 知识增强的大模型：
- 上下文知识：检索增强（RAG）
- 参数知识：知识编辑（Knowledge Editing）
🎓欢迎有意科研实习、攻读硕士、攻读博士的同学和我联系！！！
