Signal Detection under Composite Hypotheses with Identical Distributions for Signals and for Noises
Yiming Xing, Anamitra Chaudhuri, Yifan Chen
In this paper, we consider the problem of detecting signals in multiple, sequentially observed data streams, where the distribution of each stream lies in one of two common composi…

Active Hypothesis Testing for Correlated Combinatorial Anomaly Detection
Zichuan Yang, Yiming Xing
We study the problem of identifying an anomalous subset of streams under correlated noise, motivated by monitoring and security in cyber-physical systems. This problem can be viewe…
