I am a Principal Researcher of Tencent AI Lab at Seattle, working on machine learning and computer vision. Before joining Tencent, I was a tenure-track Assistant Professor in University of Central Florida (UCF). My research in UCF was supported in part by an NSF CRII award (so-PI, received in 2016) and an NSF BIGDATA award (PI, received in 2017), both of which were the first of their kinds ever granted to UCF. I actively serve on NSF panels and the program committees of computer vision conferences (CVPR, ICCV, ECCV, etc.) and machine learning conferences (ICML, NIPS, AISTATS, etc.). I was an area chair of IEEE WACV'18 and a mentor of its PhD forum. In 2015, I received a Ph.D. degree in Computer Science from the University of Southern California, where my work was partially supported by the Viterbi Fellowship.
Recent research interests: domain adaptation, reinforcement learning, and visual analytics of objects, human activities, scenes, and their attributes.

11/2018: Talk at INFORMS Special Session on Stochastic Optimization Methods and Approximation Theory in Machine Learning
"The Multiple Shades of Dropout for Discriminative and Generative Deep Neural Networks". Dropout, which independently zeros out the outputs of neurons at random, has become one of the most popular techniques in training deep neural networks due to its simplicity and remarkable effectiveness. This talk reveals multiple shades of dropout for both discriminative and generative deep neural networks, mainly covering our following works: [Li et al., NIPS'16] and [Wei, Gong, et al., ICLR'18].Slides coming soon
06/2018: Talk at CVPR The 2nd Workshop on Visual Understanding by Learning from Web Data
"Learning from Web Data and Adapting Beyond It", which inlcudes the Web data of 1) noisy labels, 2) accurate labels, and 3) multi-modalities by semi-supervised learning, curriculum learning, and kernel mean matching, respectively. It mainly covers our following works: [Ding et al., WACV'18], [Wei, Gong, et al., ICLR'18], [Gan et al., CVPR'18], [Zhang et al., ICCV'17], [Gan et al., ECCV'16], and [Sharghi et al., ECCV'16].read more: Slides
