I am a second year PhD student in Electrical Engineering at North Carolina State University. I received my bachelor’s degree in Communication Engineering from Nanjing University of Posts and Telecommunications in July 2013. My current research interests include Machine learning and text mining. Currently I am interested on sparse modeling of unstructured text information and especially on the application of sparse subspace methods on text clustering. I am also working on the Data Readiness Level(DRL) project. The project aims to use quantitative metrics to measure the value of a piece of data at a given point in a processing flow. Our proposed metrics focus on text information and will be extended to other form of information.
