Quickest Change Detection in Discrete-Time in Presence of a Covert Adversary
Amir Reza Ramtin, Philippe Nain, Don Towsley
We study the problem of covert quickest change detection in a discrete-time setting, where a sequence of observations undergoes a distributional change at an unknown time. Unlike c…

Quickest Change Detection in Continuous-Time in Presence of a Covert Adversary
Amir Reza Ramtin, Philippe Nain, Don Towsley
We investigate the problem of covert quickest change detection in a continuous-time setting, where a Brownian motion experiences a drift change at an unknown time. Unlike classical…
