Rate-Distortion-Perception Theory: Redefining the Fundamental Limits of Information Representation
Photios A. Stavrou, Giuseppe Serra, Marios Kountouris
Classical rate-distortion (RD) theory has long established the fundamental limits of lossy compression by quantifying the minimum number of bits required to represent a source unde…
Information-Theoretic Meta Dynamic Programming for Signalling and Control of POMDPs
Charalambos D. Charalambous, Stelios Louka, Photios A. Stavrou
In this paper, we study the information-theoretic characterization of simultaneous signalling and control over channels modeled by partially observable Markov decision processes (P…
Pilot-Free Optimal Control over Wireless Networks: A Control-Aided Channel Prediction Approach
Minjie Tang, Zunqi Li, Photios A. Stavrou +1
A recurring theme in optimal controller design for wireless networked control systems (WNCS) is the reliance on real-time channel state information (CSI). However, acquiring accura…
Multi-Sensor Scheduling for Remote State Estimation over Wireless MIMO Fading Channels with Semantic Over-the-Air Aggregation
Minjie Tang, Photios A. Stavrou, Marios Kountouris
In this work, we study multi-sensor scheduling for remote state estimation over wireless multiple-input multiple-output (MIMO) fading channels using a novel semantic over-the-air (…
Cost-Free Personalization via Information-Geometric Projection in Bayesian Federated Learning
Nour Jamoussi, Giuseppe Serra, Photios A. Stavrou +1
Bayesian Federated Learning (BFL) combines uncertainty modeling with decentralized training, enabling the development of personalized and reliable models under data heterogeneity a…
Learning-Augmented Perfectly Secure Collaborative Matrix Multiplication
Zixuan He, Mohammad Reza Deylam Salehi, Derya Malak +1
This paper presents a perfectly secure matrix multiplication (PSMM) protocol for multiparty computation (MPC) of over finite fields. The proposed sche…
