摘要
In this talk, we introduce our recent research on noise intialization and sampling enhancement strategies of diffusion models, spaning from image generation to video generation. Diffusion models is a class of mainstream generative modeling method for modern AIGC. Diffusion models can gradually denoise a Gaussian noise into a clean generated result, where such random Gaussian noise can naturally lead to diversitified results. What can this motivate us? We try to understand why some noise initializations are “golden noises” that can generate better results, and leverage such “golden noise” insight to further enhance diffusion sampling quality. This talk includes three parts: 1) Golden Noise for Text-to-Image Diffusion Models; 2) [ICLR 2025] Zigzag Diffusion Sampling; 3) [ICLR 2025] Leveraging Image Diffusion Models for Enhanced Video Synthesis.
演讲者介绍
I am an Assistant Professor jointly appointed by DSA Thrust and AI Thrust, Hong Kong University of Science and Technology (Guangzhou). I will also be an affiliated Assistant Professor at Dept. of CSE, Hong Kong University of Science and Technology (Clear Water Bay).

Previously, I was a researcher at Baidu Research responsible for large models and AIGC research. I obtained Ph.D. and M.E. both from The University of Tokyo, respectively. I was fortunate to be advised by Prof. Issei Sato and Prof. Masashi Sugiyama. I was also affiliated with RIKEN AIP during the Ph.D. study. Before that, I obtained Bachelor of Science from University of Science and Technology of China.

My mission is to find a way towards the science of AI. I am generally interested in understanding and solving fundamental issues of modern AI by scientific principles and methodology. My current research projects focus on foundations of machine learning and generative AI.
