< About Me />
I am currently pursuing a Ph.D. at Xiamen University under the supervision of Prof. Yang Lu. I received my master's degree from Guangdong University of Technology, where I was advised by Prof. Lunke Fei. My research interests include long-tailed learning, image generation, and adversarial attacks. So far, I have published papers in these areas. My current work focuses on visual learning under imbalanced data distributions, the robustness and controllability of generative models, and security-related challenges in deep learning systems.
