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…
An Information-Theoretic Approach to Joint Sensing and Communication
Mehrasa Ahmadipour, Mari Kobayashi, Miche`le Wigger +1
A communication setup is considered where a transmitter wishes to convey a message to a receiver and simultaneously estimates the state of that receiver through a common waveform.…
State Masking Over a Two-State Compound Channel
Sadaf Salehkalaibar, Mohammad Hossein Yassaee, Vincent Y. F. Tan +1
We consider fundamental limits for communicating over a compound channel when the state of the channel needs to be masked. Our model is closely related to an area of study known as…
Joint Sensing and Communication over Memoryless Broadcast Channels
Mehrasa Ahmadipour, Michèle Wigger, Mari Kobayashi
A memoryless state-dependent broadcast channel (BC) is considered, where the transmitter wishes to convey two private messages to two receivers while simultaneously estimating the…
