I’m currently a research scientist at AI and applied research in Meta, Inc. My work is about optimization and modeling for deep machine learning with application on recommendation system.
I got my Ph.D. degree from the Dept. of Statistics at Iowa State University advised by Dr. Zhengyuan Zhu and Dr. Jia Liu. Before that, I obtained my B.S in Mathematics from Fudan University, Shanghai, China.
Identifying the latent cluster structure based on model heterogeneity is a fundamental but challenging task arises in many machine learning applications. In this article, we study the clustered coefficient regression problem in the distributed network systems, where the data are locally collected and held by nodes.
