Jiesi Zhao

Hi, my name is Jiesi Zhao, a first year graduate student in Language Technology Institute of School of Computer Science at Carnegie Mellon University.

Before that, I got Bachelor of Engineering in Communication Engineering at Beijing University of Posts and Telecommunications.

I am interested in large scale machine learning and text mining. I'm working with Prof. Eric Xing in his Petuum project now.
