Quickest Change-point Detection in Generalized Linear Models with Variational Estimation
Jonghyeok Lee, Yao Xie
We consider quickest change-point detection in generalized linear models when the post-change parameter is unknown. Such problems arise, for example, when monitoring whether the re…

Beyond Maximum Likelihood: Variational Inequality Estimation for Generalized Linear Models
Linglingzhi Zhu, Jonghyeok Lee, Yao Xie
Generalized linear models (GLMs) are fundamental tools for statistical modeling, with maximum likelihood estimation (MLE) serving as the classical approach for parameter inference.…

Multi-rank Subspace Change-point Detection with Application in Monitoring Robotic Swarms
Jonghyeok Lee, Yao Xie, Youngser Park +3
We study real-time detection of low-rank changes in the covariance structure of high-dimensional streaming data, motivated by robotic swarm monitoring. Building on the spiked covar…
