Complementary Graph Entropy, AND Product, and Disjoint Union of Graphs
Nicolas Charpenay, Maël le Treust, Aline Roumy
In the zero-error Slepian-Wolf source coding problem, the optimal rate is given by the complementary graph entropy of the characteristic graph. It has no single-lett…
Optimal Zero-Error Coding for Computing under Pairwise Shared Side Information
Nicolas Charpenay, Maël le Treust, Aline Roumy
We study the zero-error source coding problem in which an encoder with Side Information (SI) transmits source symbols to a decoder. The decoder has SI and wants to r…
Rate-Distortion Performance of Sequential Massive Random Access to Gaussian Sources with Memory
Elsa Dupraz, Thomas Maugey, Aline Roumy +1
In Sequential Massive Random Access (SMRA), a set of correlated sources is jointly encoded and stored on a server, and clients want to access to only a subset of the sources. Since…
Transmission and Storage Rates for Sequential Massive Random Access
Elsa Dupraz, Thomas Maugey, Aline Roumy +1
This paper introduces a new source coding paradigm called Sequential Massive Random Access (SMRA). In SMRA, a set of correlated sources is encoded once for all and stored on a serv…
Operational Rate-Distortion Performance of Single-source and Distributed Compressed Sensing
Giulio Coluccia, Aline Roumy, Enrico Magli
We consider correlated and distributed sources without cooperation at the encoder. For these sources, we derive the best achievable performance in the rate-distortion sense of any…
Exact Performance Analysis of the Oracle Receiver for Compressed Sensing Reconstruction
Giulio Coluccia, Aline Roumy, Enrico Magli
A sparse or compressible signal can be recovered from a certain number of noisy random projections, smaller than what dictated by classic Shannon/Nyquist theory. In this paper, we…
