Apprentissage de métrique appliqué à la détection de changement de page Web et aux attributs relatifs

This paper introduces a novel distance metric learning framework. Working with inequality constraints involving quadruplets of images, our approach aims at efficiently modeling similarity for rich or complex semantic label relationships. We study how our metric learning scheme can be exploited in contexts such as detection of important regions in Webpages or recognition with relative attributes...

Changement climatique et toponymie. Étude de la répartition ancienne du hêtre à travers ses traces toponymiques

In this paper we evaluate the feasibility of estimating the previous distribution of a tree species, the beech, from the analysis of toponyms presently in use and referring to this species. Specialists from toponymy, agromomy and geometics have been involved. Toponyms are a precious source of information about past distribution: more than 6100 toponyms referring to beech have been detected. MOT...

Contribution à l’Etude et à la Conception d’Agents Virtuels . . .

In this thesis, besides the developing a bilateral automated negotiation model between agents, in incomplete information state, integrating the personality effects of human on the negotiation process and outcomes, we proposed an architecture of such agents (―buyer‖ or ―seller‖). To do so, a new offer generation approach of three adaptive families of tactics has been proposed as follows: the tim...
