Significant progress has been made in information retrieval covering text semantic indexing and multilingual analysis. However, developments in Arabic information retrieval did not follow the extraordinary growth of Arabic usage in the Web during the ten last years. In the tasks relating to semantic analysis, it is preferable to directly deal with texts in(More)
We investigate the possibility of using kernel clustering and data fusion techniques for solving hard combinatorial optimization problems. The proposed general paradigm aims at incorporating unsupervised kernel methods into population-based heuristics, which rely on spatial fusion of solutions, in order to learn the solution clusters from the search(More)
Résumé. Le présent article rentre dans le cadre d’un projet ambitieux qui a pour objectif l’intégration des techniques d’apprentissage aux métaheuristiques pour contribuer à la résolution des problèmes d’optimisation combinatoire NP-difficiles. L’approche proposée consiste à incorporer un apprentissage non supervisé aux métaheuristiques à population de(More)
