About Me

My name is Chengxin Liu. I am a Ph.D. student supervised by Prof. Zhiguo Cao at Huazhong University of Science and Technology (HUST). I also work closely with Prof. Hao Lu. Before that, I received my bachelor’s degree from HUST.

My research interests include computer vision and machine learning, with a particular emphasis on

• Learning with noisy labels,
• Dense prediction (e.g., object detection, object counting, and segmentation),
• Generative models.
