I am now a Ph.D. candidate at College of Information Science and Technology, The Pennsylvania State University. I work with Prof. James Z. Wang and Prof. Jia Li at IIS research lab. I received my B.Sc. degree in Mathematics from University of Science and Technology of China (USTC).

Research interest:

Past research and project experiences characterizes me as a machine learning practitioner who develops data-driven models to solve domain problems of different data — including images/videos, documents, sequences, 3D meshes, crowdsourced data, educational data — with an emphasis of mathematical rigor.

This project also develops a scalable data analytic tool, called accelerated D2-clustering, to process large scale distribution data. It could potentially leverage hundreds of CPUs with a very decent scaling efficiency (say, 70-80%).

If you are a government agency, an education institution, or a non-profit organization, we may offer you a FREE academic license of the C/MPI package to run on clusters. Please contact authors by email to discuss details. If you are commercial and would like to use our software, let us know and we will try to arrange to let you use.
