😎 About Me

I am Chengyou Jia (贾成铕), a final-year Ph.D. student in Computer Science at Xi’an Jiaotong University. I am going to be a researcher in the Hunyuan Team of Tencent (Qingyun Project). My Ph.D. advisor is Prof. Minnan Luo, and I am also working closely with Prof. Xiaojun Chang. Previously, I was a visiting student in Singapore under the supervision of Prof. Ivor, and a research intern at Shanghai AI LAB, supervised by Dr. Zhiyong Wu. I received my B.E. degree from Xi’an Jiaotong University in 2021.

I have authored several publications in top-tier conferences and journals, including CVPR, AAAI, ACL, IEEE TIP, among others. I also serve as a reviewer for esteemed conferences and journals like NIPS, ICML, CVPR, ECCV.

Research Interests

I am working in the field of CV & Multi-modal. My current research interests and past experience can be summarized as follows:

• Agentic Vision Generation: Consistent Generation, Video Generation，Reward Model and RL for visual Generation
• Multimodal Agent: GUIAgent, Multi-Agent Systems
