On Cost-Aware Designs for Sequential Hypothesis Testing
George Vershinin, Asaf Cohen, Omer Gurewitz
We introduce Cost-Aware (CA) Sequential Hypothesis Testing (CASHT), in which an active decision-maker selects sensing actions with different, random costs to identify the true hypo…
Active Sequential Hypothesis Testing with Non-Homogeneous Costs
George Vershinin, Asaf Cohen, Omer Gurewitz
We study the Non-Homogeneous Sequential Hypothesis Testing (NHSHT), where a single active Decision-Maker (DM) selects actions with heterogeneous positive costs to identify the true…
Iterative Hypothesis Pruning and Distribution-based Early Labeling for Sequential Hypothesis Testing
George Vershinin, Asaf Cohen, Omer Gurewitz
We consider the framework of Sequential Hypothesis Testing (SHT), in which a decision maker (DM) selects actions that generate samples from known, action-dependent distributions, w…
Multi-Stage Active Sequential Hypothesis Testing with Clustered Hypotheses
George Vershinin, Asaf Cohen, Omer Gurewitz
We consider the problem where an active Decision-Maker (DM) is tasked to identify the true hypothesis using as few as possible observations while maintaining accuracy. The DM colle…
Secure Adaptive Group Testing
Alejandro Cohen, Asaf Cohen, Omer Gurewitz
\emph{Group Testing} (GT) addresses the problem of identifying a small subset of defective items from a large population, by grouping items into as few test pools as possible. In \…
Secure Group Testing
Alejandro Cohen, Asaf Cohen, Omer Gurewitz
The principal goal of Group Testing (GT) is to identify a small subset of "defective" items from a large population, by grouping items into as few test pools as possible. The test…
Wiretap Channel With Causal State Information and Secure Rate-Limited Feedback
Alejandro Cohen, Asaf Cohen
In this paper, we consider the secrecy capacity of a wiretap channel in the presence of causal state information and secure rate-limited feedback. In this scenario, the causal stat…
