Invitation The organizing committee of ALCOSP'2013 is very happy to welcome you in Caen to meet renowned scholars and practitioners from all over the world. The city of Caen is the capital of Normandy, one of the most attractive European regions due to its historical and cultural richness and natural beauty. ALCOSP'2013 is mainly organized by the GREYC Lab and will take place at the Campus 1 of the University of Caen Basse-Normandie. Aims In control and signal processing, adaptation and learning are natural tools to cope with real-time changes in the dynamical behaviour of signals and systems. In this respect, there has been an increasing interest in the use of computationally intelligent methods as potential tools to improve adaptation. This workshop has the goal of bringing together researchers and practitioners interested in adaptation and learning, providing them with a forum for presentation of recent developments and assessment of the most promising trends for future research. It is organized under the auspices of the International Federation of Automatic Control (IFAC). In IFAC, this workshop is one of the rare regular events gathering potential actors from both the control and the signal processing communities. It is rooted in a long standing IFAC activity since ALCOSP 2013 is the 11th in a series originated in San Francisco (1983) and continued in Lund (1986), Glasgow (1989), Grenoble (1992), Budapest (1995), Glasgow (1998), Cernobbio-Come (2001), Katayama (2004), Saint-Petersburg (2007) and Antalya (2010).
