Je suis très content d’annoncer que l’article suivant :
L1-compressive sensing: exact optimization a la Dantzig-Wolfe. A. Borghi, J. Darbon and S. Peyronnet.
a été accepté à SiPS 2010 (2010 IEEE Workshop on Signal Processing Systems).
Dans cet article, nous présentons un algorithme efficace pour calculer une solution exacte d’un problème de compressive sensing en norme . Pour cela nous utilisons une reformulation du problème via une décomposition de Dantzig-Wolfe modifié. Les résultats numériques montrent une amélioration substantielle par rapport aux méthodes standards de programmation linéaire.

It could be useful for everybody, so here is the trick:

The Second Symposium on Innovations in Computer Science (ICS 2011) will be held in Beijing, China, January 7-9, 2011, with a welcome reception on January 7.
Innovations in Computer Science (ICS) is a new conference in theoretical computer science (TCS), broadly construed. ICS seeks to promote research that carries a strong conceptual message (e.g., introducing a new concept or model, opening a new line of inquiry within traditional or cross-disciplinary areas, or introducing new techniques or new applications of known techniques). ICS welcomes all submissions, whether aligned with [...]

BACKGROUND, AIM AND SCOPE
=========================
Emerging trends in concurrency theory require the definition of models and languages adequate for the design and management of new classes of applications, mainly to program either WANs (like Internet) or smaller networks of mobile and portable devices (which support applications based on a dynamically reconfigurable communication structure). Due to the openness of these systems, new critical aspects come into play, such as the need to deal [...]

The aim of this eleventh edition of the conference series on Web Information Systems Engineering is to provide an international forum for researchers, professionals, and industrial practitioners to share their knowledge in the rapidly growing area of Web technologies, methodologies and applications. Previous WISE conferences were held in Hong Kong, China (2000), Kyoto, Japan (2001), Singapore (2002), Roma, Italy (2003), Brisbane, Australia (2004), New York, USA (2005), Wuhan, China (2006), Nancy, France (2007), Auckland, New Zealand (2008), and Poznan, Poland (2009).
The proceedings of WISE 2010 will be published in 2 [...]

WSDM (pronounced “wisdom”) is the premier international ACM conference covering research in the areas of search and data mining on the Web. The 4th ACM WSDM Conference will take place in Hong Kong, during February 9-12, 2011.WSDM publishes original, high quality papers and presentations related to search and data mining on the Web and the Social Web, with an emphasis on practical but principled novel models of search, retrieval and data mining, algorithm design and analysis, economics implications, and in-depth experimental analysis of accuracy and performance.
WSDM2011 will have keynotes, invited talks, full paper presentations, posters, tutorials, workshops, social events, etc. [...]
