Yichen Liu

I am an AI researcher in SenseTime. I obtained the Bachelor Degree of both Computer Science and Mathematics from the Hong Kong University of Science and Technology(HKUST). I also obtained the MPhil Degree of Computer Science, supervised by Prof. Chi-Keung Tang and Prof. Yu-Wing Tai. My research interests are in the areas of computer vision and machine learning, especially 3D vision. Currently I am focusing on diffusion model and multi-modal LLM.

Feel free to contact me through email for any question!
