53rd Annual Allerton Conference on Communication, Control, and Computing (Allerton)
作者: Kumar, Santhosh Vem, Avinash Narayanan, Krishna Pfister, Henry D. Texas A&M Univ Dept Elect & Comp Engn College Stn TX 77843 USA Duke Univ Dept Elect & Comp Engn Durham NC 27706 USA
The focus of this article is on low-complexity capacity-achieving coding schemes for write-once memory (WOM) systems. The construction is based on spatially-coupled compound LDGM/LDPC codes. Both noiseless systems and... 详细信息

53rd Annual Allerton Conference on Communication, Control, and Computing (Allerton)
作者: Lian, Mengke Pfister, Henry D. Duke Univ Dept Elect & Comp Engn Durham NC 27706 USA
This work considers the compressed sensing (CS) of i.i.d. signals with sparse measurement matrices and belief-propagation (BP) reconstruction. In general, BP reconstruction for CS requires the passing of messages that... 详细信息

JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2015年 第5期000卷 P05013-P05013页
作者: Barbier, Jean Schuelke, Christophe Krzakala, Florent Ecole Normale Super CNRS UMR 8550 Phys Stat Lab F-75231 Paris France Univ Paris 06 F-75231 Paris France Univ Paris 06 Sorbonne Univ UMR 8550 F-75231 Paris France Univ Paris Diderot Sorbonne Paris Cite F-75205 Paris France Univ Roma La Sapienza Dipartimento Fis I-00185 Rome Italy
We study the behavior of approximate message-passing (AMP), a solver for linear sparse estimation problems such as compressed sensing, when the i.i.d matrices-for which it has been specifically designed-are replaced b... 详细信息

JOURNAL OF STATISTICAL MECHANICS-THEORY AND EXPERIMENT 2015年 第11期2015卷 1-1页
作者: Schuelke, Christophe Caltagirone, Francesco Zdeborova, Lenka Univ Paris 07 Sorbonne Paris Cite F-75013 Paris France Univ Roma La Sapienza Dipartimento Fis I-00185 Rome Italy Ecole Normale Super CNRS Lab Phys Stat UMR 8550 F-75231 Paris France Univ Paris 06 F-75231 Paris France CEA Saclay Inst Phys Theor F-91191 Gif Sur Yvette France CNRS URA 2306 F-91191 Gif Sur Yvette France
The ubiquity of approximately sparse data has led a variety of communities to take great interest in compressed sensing algorithms. Although these are very successful and well understood for linear measurements with a... 详细信息

作者: Shiraki, Yoshifumi Kabashima, Yoshiyuki NTT Corp NTT Commun Sci Lab Atsugi Kanagawa 2430198 Japan Tokyo Inst Technol Dept Computat Intelligence & Syst Sci Yokohama Kanagawa 2268502 Japan
The distributed compressed sensing framework provides an efficient compression scheme of multichannel signals that are sparse in some domains and highly correlated with one another. In particular, a signal model calle... 详细信息

IEEE TRANSACTIONS ON INFORMATION THEORY 2014年 第1期60卷 191-211页
作者: Halabi, Nissim Even, Guy Tel Aviv Univ Sch Elect Engn IL-69978 Tel Aviv Israel
We consider decoding of binary linear Tanner codes using message-passing iterative decoding and linear-programming (LP) decoding in memoryless binary-input output-symmetric (MBIOS) channels. We present new certificate... 详细信息

PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA 2014年 第51期111卷 18144-18149页
作者: Zhang, Pan Moore, Cristopher Santa Fe Inst Santa Fe NM 87501 USA
Modularity is a popular measure of community structure. However, maximizing the modularity can lead to many competing partitions, with almost the same modularity, that are poorly correlated with each other. It can als... 详细信息
