Zhengwentai SUN

Ph.D. Student | Generative Models | Human-Centric AI

I am Zhengwentai SUN (孙正文泰), a Ph.D. student at The Chinese University of Hong Kong, Shenzhen, supervised by Prof. Xiaoguang Han. I completed my MPhil degree at The Hong Kong Polytechnic University, where I was supervised by Prof. Tracy Mok. I obtained my Bachelor's degree from the University of Electronic Science and Technology of China. My research focuses on generative models such as GANs and Diffusion models, particularly their applications in human-centric tasks. Additionally, I am exploring Large Language Models (LLMs) and their interaction with human users and generative vision models.
