On the Computation of the Gaussian Rate-Distortion-Perception Function
Giuseppe Serra, Photios A. Stavrou, Marios Kountouris
In this paper, we study the computation of the rate-distortion-perception function (RDPF) for a multivariate Gaussian source under mean squared error (MSE) distortion and, respecti…
Indirect Rate Distortion Functions with -Separable Distortion Criterion
Photios A. Stavrou, Yanina Shkel, Marios Kountouris
We consider a remote source coding problem subject to a {distortion function}. Contrary to the use of the classical separable distortion criterion, herein we consider the more gene…
Computation of Rate-Distortion-Perception Function under f-Divergence Perception Constraints
Giuseppe Serra, Photios A. Stavrou, Marios Kountouris
In this paper, we study the computation of the rate-distortion-perception function (RDPF) for discrete memoryless sources subject to a single-letter average distortion constraint a…
Real-time Remote Reconstruction of a Markov Source and Actuation over Wireless
Mehrdad Salimnejad, Marios Kountouris, Nikolaos Pappas
In this work, we study the problem of real-time tracking and reconstruction of an information source with the purpose of actuation. A device monitors an -state Markov process an…
Goal-oriented Policies for Cost of Actuation Error Minimization in Wireless Autonomous Systems
Emmanouil Fountoulakis, Nikolaos Pappas, Marios Kountouris
We consider the minimization of the cost of actuation error under resource constraints for real-time tracking in wireless autonomous systems. A transmitter monitors the state of a…
When is Importance Weighting Correction Needed for Covariate Shift Adaptation?
Davit Gogolashvili, Matteo Zecchin, Motonobu Kanagawa +2
This paper investigates when the importance weighting (IW) correction is needed to address covariate shift, a common situation in supervised learning where the input distributions…
