Markovian dynamics of single-rebit open quantum systems with applications to colour perception
Michel Berthier, Gabriel Niebel, Edoardo Provenzi
This paper investigates the Markovian dynamics of open two-state quantum systems defined over the real numbers (rebits). Two main objectives are pursued. First, we present a compre…
Impact of Sociality Regimes on Quality of Service and Energy Efficiency in Cell-Free MIMO Networks
Ala Eddine Nouali, Mohamed Sana, Jean-Paul Jamont
The cell-free architecture represents a significant advancement in network design, where each User Equipment (UE) is served by a group of distributed Access Points (APs), aimed at…
CARDIE: clustering algorithm on relevant descriptors for image enhancement
Giulia Bonino, Luca Alberto Rizzo
Automatic image clustering is a cornerstone of computer vision, yet its application to image enhancement remains limited, primarily due to the difficulty of defining clusters that…
Wideband Gaussian Noise Model of Nonlinear Distortions From Semiconductor Optical Amplifiers
Hartmut Hafermann
A wideband Gaussian Noise Model of the nonlinear noise power spectral density is developed for a single semiconductor optical amplifier as described by the Agrawal model. A simple,…
SAIL: Self-supervised Albedo Estimation from Real Images with a Latent Diffusion Model
Hala Djeghim, Nathan Piasco, Luis Roldão +4
Intrinsic image decomposition aims at separating an image into its underlying albedo and shading components, isolating the base color from lighting effects to enable downstream app…
Differentially Private Policy Gradient
Alexandre Rio, Merwan Barlier, Igor Colin
Motivated by the increasing deployment of reinforcement learning in the real world, involving a large consumption of personal data, we introduce a differentially private (DP) polic…
