Optimal Nested Test Plan for Combinatorial Quantitative Group Testing
Chao Wang, Qing Zhao, Chen-Nee Chuah
We consider the quantitative group testing problem where the objective is to identify defective items in a given population based on results of tests performed on subsets of the po…
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…
Indexability of Restless Bandit Problems and Optimality of Whittle's Index for Dynamic Multichannel Access
Keqin Liu, Qing Zhao
We consider a class of restless multi-armed bandit problems (RMBP) that arises in dynamic multichannel access, user/server scheduling, and optimal activation in multi-agent systems…
