Yanghao Wang「汪阳昊」

I am a second-year PhD student of LONG Group, Hong Kong University of Science and Technology, fortunately advised by Prof. Long Chen.

Before that, I obtained my M.S. degree from NTU (Singapore), where I was advised by Prof. Hanwang Zhang in Machine Reasoning and Learning Lab (MReal Lab). I got my B.S. degree from Sichuan University.

I am fortunate to have internships at WeChat, Tiktok and 4Paradigm.

Research Interests

My current research focuses on Controllable Visual Generation, especially image and video generation driven by cross-modal signals. Meanwhile, I am broadly interested in Computer Vision, Multimodal Learning, and Machine Learning.

Selected Publications
NoOp
Noise Matters: Optimizing Matching Noise for Diffusion Classifiers
Yanghao Wang, Long Chen
NeurIPS, 2025
paper / code

We proposed a novel Noise Optimization (NoOp) method to learn matching noise for Diffusion Classifiers. By using an optimized noise, the performance (accuracy and efficiency) of the Diffusion Classifier can be significantly improved.

Diff-II
Inversion Circle Interpolation: Diffusion-based Image Augmentation for Data-scarce Classification
Yanghao Wang, Long Chen
CVPR, 2025
paper / code

We proposed a novel Diffusion-based Inversion Interpolation DA method called Diff-II, which can generate faithful and diverse samples to expand the original training set in data-scarce scenarios.

RandBox
Random Boxes Are Open-world Object Detectors
Yanghao Wang, Zhongqi Yue, Xian-Sheng Hua, Hanwang Zhang
ICCV, 2023
paper / code

We showed that classifiers trained with random region proposals achieve state-of-the-art Open-world Object Detection with our designed matching score.
