Yunchao Wei 魏云超

I am currently a Postdoc Researcher in Prof. Thomas Huang's Image Formation and Professing (IFP) group at Beckman Institute, University of Illinois Urbana-Champaign (UIUC). I received PhD from Beijing Jiaotong University, advised by Prof. Zhao Yao. I was a Visiting Student from Nov. 2013 to Nov. 2015 in the Learning and Vision (LV) Research Group of National University of Singapore (NUS), working with Prof. Shuicheng Yan. I was a Postdoc Researcher from July 2016 to Sept.2017 in the LV Research Group of NUS, working with Prof. Jiashi Feng.

Research Interests

My general research interest is to develop deep learning algorithms for challenging computer vision and multimedia problems.
Recently, I focus on:

  • Weakly supervised object detection and semantic segmentation
  • Video analysis, including detection and tracking
  • Multi-label classification
  • Multi-modal analysis

News

  • NUS-Qihoo-UIUC_DPNs team won the 2nd places in all four video-related tracks in ILSVRC 2017.
  • Two papers accepted in ACM MM 2017 and one paper accepted in ICCV 2017.
  • Three papers accepted in CVPR 2017 with one oral and one spotlight.
  • One paper accepted in ICME 2017.
