Adaptive Privacy of Sequential Data Releases Under Collusion
Sophie Taylor, Praneeth Kumar Vippathalla, Justin Coon
The fundamental trade-off between privacy and utility remains an active area of research. Our contribution is motivated by two observations. First, privacy mechanisms developed for…
On the Entropy of a Random Geometric Graph
Praneeth Kumar Vippathalla, Justin P. Coon, Mihai-Alin Badiu
In this paper, we study the entropy of a hard random geometric graph (RGG), a commonly used model for spatial networks, where the connectivity is governed by the distances between…
RIS-Assisted Millimeter Wave Communications for Indoor Scenarios: Modeling and Coverage Analysis
Zhi Chai, Jiajie Xu, Justin P. Coon +1
Millimeter wave (mmWave) communications and reconfigurable intelligent surfaces (RIS) are two critical technologies for next-generation networks, especially in dense indoor environ…
Joint Beamforming with Extremely Large Scale RIS: A Sequential Multi-Agent A2C Approach
Zhi Chai, Jiajie Xu, Justin P Coon +1
It is a challenging problem to jointly optimize the base station (BS) precoding matrix and the reconfigurable intelligent surface (RIS) phases simultaneously in a RIS-assisted mult…
The Asymptotic Behaviour of Information Leakage Metrics
Sophie Taylor, Praneeth Kumar Vippathalla, Justin P. Coon
Information theoretic leakage metrics quantify the amount of information about a private random variable that is leaked through a correlated revealed variable . They can be…
Rate-Distortion-Perception Function of Bernoulli Vector Sources
Praneeth Kumar Vippathalla, Mihai-Alin Badiu, Justin P. Coon
In this paper, we consider the rate-distortion-perception (RDP) trade-off for the lossy compression of a Bernoulli vector source, which is a finite collection of independent binary…
