Espaces de représentations complètement réductibles

We study some geometric properties of actions on nonpositively curved spaces related to complete reducibility and semisimplicity, focusing on representations of a finitely generated group Γ in the group G of rational points of a reductive group over a local field, acting on the associated space (symmetric space or affine building). We prove that the space of completely reducible classes is the ...

Les systèmes de classeurs

Learning Classifier Systems (LCSs) are rule-based systems that automatically build their ruleset. Initially, LCSs were dedicated to the modelling of the emergence of cognitive abilities thanks to adaptive mechanisms, particularly evolutionary processes. After a renewal of the field more focused on learning, LCSs have been reconsidered as sequential decision problem solving systems endowed with ...

Patterns de coopération de systèmes d'information

Cooperation of heterogeneous legacy information systems in organizations is a reality, offering to users a unified access to heterogeneous and distributed information. Our goal is to capitalize design knowledge involved in cooperative application development and to define cooperation patterns adapted from Fowler’s analysis patterns. These patterns, derived from ACSIS cooperative architecture, a...
