Dynamic change-point detection using similarity networks
Shanshan Cao, Yao Xie
From a sequence of similarity networks, with edges representing certain similarity measures between nodes, we are interested in detecting a change-point which changes the statistic…
Data-Driven Threshold Machine: Scan Statistics, Change-Point Detection, and Extreme Bandits
Shuang Li, Yao Xie, Le Song
We present a novel distribution-free approach, the data-driven threshold machine (DTM), for a fundamental problem at the core of many learning tasks: choose a threshold for a given…
Sequential Low-Rank Change Detection
Yao Xie, Lee Seversky
Detecting emergence of a low-rank signal from high-dimensional data is an important problem arising from many applications such as camera surveillance and swarm monitoring using se…
Change Detection via Affine and Quadratic Detectors
Yang Cao, Vincent Guigues, Anatoli Juditsky +2
The goal of the paper is to develop a specific application of the convex optimization based hypothesis testing techniques developed in A. Juditsky, A. Nemirovski, "Hypothesis testi…
Detecting weak changes in dynamic events over networks
Shuang Li, Yao Xie, Mehrdad Farajtabar +2
Large volume of networked streaming event data are becoming increasingly available in a wide variety of applications, such as social network analysis, Internet traffic monitoring a…
