Yafei Yang

I am a fourth-year PhD student (HKPFS) at Department of Computing at The Hong Kong Polytechnic University, supervised by Prof. Bo Yang.

Previously, I got my B.Eng degree from Department of Computer Science at The University of Hong Kong with First Class Honors, double majoring in Finance.

In my undergraduate study, I have been exchanged to UC Berkeley and National University of Singapore.

My general research interests lie in computer vision and machine learning. Currently I am focusing on object-centric representation learning, covering the segmentation and generation of objects.
