Leveraging Code Automorphisms for Improved Syndrome-Based Neural Decoding
Raphaël Le Bidan, Ahmad Ismail, Elsa Dupraz +1
Syndrome-based neural decoding (SBND) has emerged as a promising deep learning approach for soft-decision decoding of high-rate, short-length codes. However, this approach still ha…
Non-Asymptotic Achievable Rate-Distortion Region for Indirect Wyner-Ziv Source Coding
Jiahui Wei, Philippe Mary, Elsa Dupraz
In the Wyner-Ziv source coding problem, a source has to be encoded while the decoder has access to side information . This paper investigates the indirect setup, in which a…
Learning Variable Node Selection for Improved Multi-Round Belief Propagation Decoding
Ahmad Ismail, Raphaël Le Bidan, Elsa Dupraz +1
Error correction at short blocklengths remains a challenge for low-density parity-check (LDPC) codes, as belief propagation (BP) decoding is suboptimal compared to maximum-likeliho…
Practical Short-Length Coding Schemes for Binary Distributed Hypothesis Testing
Ismaila Salihou Adamou, Elsa Dupraz, Reza Asvadi +1
This paper addresses the design of practical shortlength coding schemes for Distributed Hypothesis Testing (DHT). While most prior work on DHT has focused on informationtheoretic a…
Doing More With Less: Towards More Data-Efficient Syndrome-Based Neural Decoders
Ahmad Ismail, Raphaël Le Bidan, Elsa Dupraz +1
While significant research efforts have been directed toward developing more capable neural decoding architectures, comparatively little attention has been paid to the quality of t…
Covering Codes as Near-Optimal Quantizers for Distributed Testing Against Independence

The design of communication systems dedicated to machine learning tasks is one key aspect of goal-oriented communications. In this framework, this article investigates the interpla…
An Information-Spectrum Approach to Distributed Hypothesis Testing for General Sources
Ismaila Salihou Adamou, Elsa Dupraz, Tad Matsumoto
This paper investigates Distributed Hypothesis testing (DHT), in which a source is encoded given that side information is available at the decoder only. B…
Optimizing the Energy Efficiency of Unreliable Memories for Quantized Kalman Filtering
Jonathan Kern, Elsa Dupraz, Abdeldjalil Aïssa-El-Bey +2
This paper presents a quantized Kalman filter implemented using unreliable memories. We consider that both the quantization and the unreliable memories introduce errors in the comp…
Energy Optimization of Faulty Quantized Min-Sum LDPC Decoders
Mohamed Yaoumi, Jeremy Nadal, Elsa Dupraz +2
The objective of this paper is to minimize the energy consumption of a quantized Min-Sum LDPC decoder, by considering aggressive voltage downscaling of the decoder circuit. Since l…

Fangping Ye, Elsa Dupraz, Zeina Mheich +1
This paper considers the problem of source coding with side information at the decoder, also called Slepian-Wolf source coding scheme. In practical applications of this coding sche…
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…
