About Me
I am a Ph.D student in College of Computer Science and Technology, Zhejiang University, advised by Jianling Sun and Chenghao Liu. My research interests are debiasing implicit feedback, large generative models (diffusion models, LLM for coding, prompting) and time series processing. I have a passion to use mathematics to model the world and master the data.
