Research interests: machine learning, data mining, information retrieval, and
computer vision. My PhD thesis is dedicated to large-scale machine learning algorithms
for classification and search. Currently, I am working on combinatorial, parallel, and distributed optimization methods to tackle noise/outlier present, high-dimensional, and large-scale learning problems. I am particularly interested in developing binary coding
and hashing techniques to handle big data.
l Our SIGIR’16 paper Discrete Collaborative Filtering wins the Best Paper Award Honorable Mention!
l We give a tutorial of “Compact Features for Visual Search” at CVPR 2016.
l Hashing by Deep Learning, which is a section of our hashing survey paper appearing in Proceedings of the IEEE 2015.
l I act as a guest editor of Neurocomputing Special Issue on Advanced Learning for Large-Scale Heterogeneous Computing 2016.
l I am teaching the Computer Vision course at Stevens Institute of Technology in 2015 Spring.
l I act as a guest editor of ACM TIST Special Issue on Mobile Social Multimedia Analytics in the Big Data Era 2015.
l One paper is accepted by KDD’15.
l Four papers are accepted by CVPR’15, and two papers are accepted by ICCV’15.
l Two papers are accepted by AAAI’15, and two papers are accepted by IJCAI’15.
l I taught the Database Mining course at RPI in 2014 Fall.
l Two papers were accepted by NIPS’14, and one is spotlight oral.
l Two papers were accepted by CVPR’14 oral sessions.
l One paper was accepted by ECCV’14, and one paper was accepted by AAAI’14.
l One paper won the Best Paper Travel Award of IEEE International Symposium on Biomedical Imaging (ISBI), 2014.
l Three papers were accepted by ICCV’13. Thanks to the support of Josef Raviv Memorial Postdoctoral Fellowship.
l I acted as a guest editor of Neurocomputing Special Issue on Learning for 3D Understanding 2013.
l I won Jury Award for best thesis of Department of Electrical Engineering, Columbia University, 2013.
l I passed my PhD defense on August 24th, 2012.
l I won Josef Raviv Memorial Postdoctoral Fellowship 2012-2013.
l I was awarded Facebook Fellowship 2011-2012 (one of five winners worldwide). Thanks to Facebook!
