Title: Evolutionary approach for Bayesian networks structure learning

Abstract:
In this thesis, we propose a study of the problem of learning the structure of a bayesian network through the use of evolutionary methods.We first designed a genetic algorithm to search the space of structures before establishing various strategies aiming at improving the performances of this algorithm. We consequently developed a search strategy aiming at exploiting the properties of the space of completed partially oriented graphs using a sequential niching principle which we later hybridized with an island model scheme. Another method defines a distribution probability over the mutation operations which are applied to the individuals and that is a function of the qualitative results of previously applied operations.
