Chong You

I am a fifth year PhD student in Electrical and Computer Engineering at Johns Hopkins University, under the supervision of Prof. Rene Vidal. I also work closely with Prof. Daniel Robinson.

Prior to coming to Hopkins, I got two B.S. degrees in electrical engineering as well as in applied mathematics in 2009 at Peking University. Then I got my M.S. degree in 2012 at Peking University, under the supervision of Prof. Bocheng Zhu.

Research

I am currently interested in developing robust, efficient and provable algorithms for analyzing visual data with intrinsic low-rank structures. Specifically, we have designed algorithms to cluster data lying in a union of subspaces in large datasets (~1 million instances) with guaranteed correctness. Part of our work has been published at ICML’15, CVPR’16 and CVPR'17.

Generally, my research interests lie in the interplay of optimization, signal processing and statistics with applications to computer vision tasks. For the upcoming research, I am keen on developing practical technologies for understanding visual data. I have recently been working on developing tools for age estimation from face images in countries with limited vital registration.
