PhD Student, Advanced to Candidacy
Zehua Lai is a third-year Ph.D. student at the Committee on Computational and Applied Mathematics. Prior to coming to Chicago, he received his bachelor's degree in Economics and Mathematics at Tsinghua University. His research interest is to employ techniques in pure and applied mathematics to deepen our understanding of computational and statistical problems in modern machine learning. He is also interested in statistical physics and applied algebraic geometry.
Also, Zehua recently published the paper "Recht–Re Noncommutative Arithmetic-Geometric Mean Conjecture is False" in the International Conference on Machine Learning (ICML). A preprint "Simpler Grassmannian optimization" is posted on arXiv https://arxiv.org/abs/2009.13502.
