(Bill) Yuchen Lin

I am a 2nd-year Ph.D. student in Computer Science at the University of Southern California (USC), working with Prof. Xiang Ren who leads the Intelligence and Knowledge Discovery (INK) Research Lab. Pirorly, I got my bachelor degree at the IEEE Honor Class of Shanghai Jiao Tong University (SJTU), supervised by Prof. Kenny Q. Zhu.

My research focuses on natural language processing and knowledge-based AI. Specifically, I am working on Information Extraction and Commonsense Reasoning, with a focus on using less labeled data (e.g. transfer learning, active learning) and improving model transparency with structural inductive bias (e.g. graph networks).

I am looking for a research internship in 2020 summer.
