EVaR-Optimal Arm Identification in Bandits
Mehrasa Ahmadipour, Aurélien Garivier
We study the fixed-confidence best arm identification (BAI) problem within the multi-armed bandit (MAB) framework under the Entropic Value-at-Risk (EVaR) criterion. Our analysis co…
Identifying the Best Transition Law
Mehrasa Ahmadipour, élise Crepon, Aurélien Garivier
Motivated by recursive learning in Markov Decision Processes, this paper studies best-arm identification in bandit problems where each arm's reward is drawn from a multinomial dist…
An Information-Theoretic Approach to Collaborative Integrated Sensing and Communication for Two-Transmitter Systems
Mehrasa Ahmadipour, Michèle Wigger
This paper considers information-theoretic models for integrated sensing and communication (ISAC) over multi-access channels (MAC) and device-to-device (D2D) communication. The mod…
Integrated Communication and Receiver Sensing with Security Constraints on Message and State
Mehrasa Ahmadipour, Michèle Wigger, Shlomo Shamai
We study the state-dependent wiretap channel with non-causal channel state informations at the encoder in an integrated sensing and communications (ISAC) scenario. In this scenario…
Strong Converses for Memoryless Bi-Static ISAC
Mehrasa Ahmadipour, Michele Wigger, Shlomo Shamai
The paper characterizes the fundamental limits of integrated sensing and communication (ISAC) systems with a bi-static radar, where the radar receiver is located close to the trans…
Coding for Sensing: An Improved Scheme for Integrated Sensing and Communication over MACs
Mehrasa Ahmadipour, Michele Wigger, Mari Kobayashi
A memoryless state-dependent multiple-access channel (MAC) is considered, where two transmitters wish to convey their messages to a single receiver while simultaneously sensing (es…
