Sequential Lossy Compression With Causal Conditional Perception

Photios A. Stavrou, Zixuan He

In this paper, we study sequential lossy compression under a causal conditional perception criterion comparing source and reconstruction distributions given the same reconstruction…

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…

Information Entropy-Based Scheduling for Communication-Efficient Decentralized Learning

Jaiprakash Nagar, Zheng Chen, Marios Kountouris +1

This paper addresses decentralized stochastic gradient descent (D-SGD) over resource-constrained networks by introducing node-based and link-based scheduling strategies to enhance…
