Yuanzhe (Richard) Pang

Hello. I am a computer science Ph.D. candidate in the Courant Institute of Mathematical Sciences at New York University. I am a member of the Machine Learning for Language (ML²) group (subset of the CILVR group). I am advised by Prof. He He and Prof. Kyunghyun Cho. I also frequently collaborated with Prof. Sam Bowman. Since October 2022, I have been a Visiting Researcher at Meta AI (FAIR) mentored by Dr. Jason Weston and Dr. Stephen Roller.

My research focuses on natural langauge processing and machine learning. Specifically, recent interests include text generation, structured prediction, and long text understanding.

Prior to my Ph.D., I graduated from the University of Chicago (B.S. in mathematics and B.S. in computer science). In Chicago, my advisor was Prof. Kevin Gimpel at Toyota Technological Institute at Chicago (TTIC) and the University of Chicago. In Summer 2020, I was a Research Intern at Google Research New York; in Summer 2021, I was a Research Intern at Google Brain.

tl;dr: GOLD does not maximize the expected reward. It maximizes the expected reward of training examples only.
