Yuda Song

Hi, I am first year PhD student at Machine Learning Department, Carnegie Mellon University . I am coadvise by Aarti Singh and Drew Bagnell. I am also closely working with Wen Sun. I finished my master degree in MLD, advised by Kris Kitani. I completed my undergraduate at UC San Diego with CS and Math double major and I was advised by Sicun Gao.

I am broadly interested in machine learning, especially reinforcement learning. I am current focusing on provably statistically and computationally efficient settings and algorithms in RL.
