Yichong Xu

I'm a Ph.D. student in Machine Learning Department of Carnegie Mellon University. I work on machine learning, especially on interactive learning problems, with my advisors Artur Dubrawski and Aarti Singh. I also work on NLP tasks, especially natural language understanding. Previously I have done research on deep learning/computer vision and game theory.
