Approximate message-passing with spatially coupled structured operators, with applications to compressed sensing and sparse superposition codes
Jean Barbier, Christophe Schülke, Florent Krzakala
We study the behavior of Approximate Message-Passing, a solver for linear sparse estimation problems such as compressed sensing, when the i.i.d matrices -for which it has been spec…
The hard-core model on random graphs revisited
Jean Barbier, Florent Krzakala, Lenka Zdeborová +1
We revisit the classical hard-core model, also known as independent set and dual to vertex cover problem, where one puts particles with a first-neighbor hard-core repulsion on the…
Robust error correction for real-valued signals via message-passing decoding and spatial coupling
Jean Barbier, Florent Krzakala, Lenka Zdeborová +1
We revisit the error correction scheme of real-valued signals when the codeword is corrupted by gross errors on a fraction of entries and a small noise on all the entries. Combinin…
