Online Score Statistics for Detecting Clustered Change in Network Point Processes
Rui Zhang, Haoyun Wang, Yao Xie
We consider online monitoring of the network event data to detect local changes in a cluster when the affected data stream distribution shifts from one point process to another wit…
Testing Rank of Incomplete Unimodal Matrices
Rui Zhang, Junting Chen, Yao Xie +2
Several statistics-based detectors, based on unimodal matrix models, for determining the number of sources in a field are designed. A new variance ratio statistic is proposed, and…
On characteristic rank for matrix and tensor completion
Alexander Shapiro, Yao Xie, Rui Zhang
In this lecture note, we discuss a fundamental concept, referred to as the {\it characteristic rank}, which suggests a general framework for characterizing the basic properties of…
Online detection of cascading change-points
Rui Zhang, Yao Xie, Rui Yao +1
We propose an online detection procedure for cascading failures in the network from sequential data, which can be modeled as multiple correlated change-points happening during a sh…
Goodness-of-fit tests on manifolds
Alexander Shapiro, Yao Xie, Rui Zhang
We develop a general theory for the goodness-of-fit test to non-linear models. In particular, we assume that the observations are noisy samples of a submanifold defined by a \yao{s…
