Ph.D. in Electrical Engineering: Systems
University of Michigan, Ann Arbor
I am a researcher in Media Analytics group of NEC Laboratories America since July 2015. Before joining NEC lab, I completed my Ph.D. at University of Michigan under the supervision by professor Honglak Lee. I have broad interest in machine learning and computer vision. Specifically, my research focuses on supervised and unsupervised deep representation learning with applications to computer vision, audio recognition, and text processing, using graphical models that are invariant to many factors of variation for robust perception from complex and multimodal data.
