Yi He
I am an assistant professor of Computer Science at Old Dominion University, since Fall 2021. I received my Ph.D from the Center for Advanced Computer Studies (CACS) at the University of Louisiana at Lafayette in 2020, advised by Dr. Xindong Wu. Before that, I received the B.E. degree from Harbin Institute of Technology (HIT), China, in 2013. My research interests lie broadly in data mining, machine learning, and optimization theory and specifically in online learning, real-time data analytics, representation learning, graph mining, recommender systems, and explainable AI. I am a recipient of the IEEE TCII Volunteer Award 2022 and the NSF CRII Award 2023. I am looking for self-motivated Ph.D. and M.S. students to join my lab, please find details here.
