Asymptotically Optimal Anomaly Detection via Sequential Testing
Kobi Cohen, Qing Zhao
Sequential detection of independent anomalous processes among K processes is considered. At each time, only M processes can be observed, and the observations from each chosen proce…

Optimal Index Policies for Anomaly Localization in Resource-Constrained Cyber Systems
Kobi Cohen, Qing Zhao, Ananthram Swami
The problem of anomaly localization in a resource-constrained cyber system is considered. Each anomalous component of the system incurs a cost per unit time until its anomaly is id…

Active Hypothesis Testing for Quickest Anomaly Detection
Kobi Cohen, Qing Zhao
The problem of quickest detection of an anomalous process among M processes is considered. At each time, a subset of the processes can be observed, and the observations from each c…
