π§ About Me
Hi there! I am a final-year PhD student in Computer Science at HKU, under the supervision of Prof. Chao Huang. Before that, I received my Bachelorβs degree at Harbin Institute of Technology in July 2022.
Research Interests:
My research interests encompass recommendation systems, large language models, and intelligent agents. I am committed to tackling the challenges faced by recommendation systems across various scenarios, utilizing technologies such as self-supervised learning and large language models. Looking ahead, I plan to delve into topics related to intelligent agents, with the goal of developing personalized and efficient agent systems.
Ongoing Project:
GUI Agent.
I warmly welcome collaborators who share an interest in these related areas.
