Suivi du transport des marchandises en ville : un nouveau pacte entre enquêtes statistiques et modélisation

Un cadre de modélisation des relations entre les réactions rationnelles et comportementales des agents assistants conversationnels

In order to improve the users’ acceptability of conversational assistant agents (CAA), the agents should be supplied with behavioral models, which in turn interact with their basic rational reasoning process. We present here a flexible modeling framework, dedicated to the study of the relationships between the rational and behavioral reactions of CAA. This framework is then used to support the ...

Coopération entre un robot mobile et des caméras d'ambiance pour le suivi multi-personnes

In this paper, we present a cooperative perception system between wall mounted cameras and sensors on-board a mobile robot to : (i) track and follow a given target person wearing a Radio Frequency Identification (RFID) tag, and (ii) facilitate navigation in the presence of passers-by during the execution of this mission. We employ a "trackingby-detection" approach within a Particle Filtering st...

Un cas de « polysémie logique » : modélisation de noms d'action en français ambigus entre processus et artefact

This paper describes a modeling in a logical framework of the semantic content of a class of action nouns in French that are ambiguous between a processive interpretation and a resultative one in which these nouns refer to new objects in the world that are created by the process artefacts. The first part of the paper is about an explanation of the properties that show why these ambiguous action...

Et Aveugles En Traitement Du Signal Et Des Images

We consider the problem of subspace estimation in aBayesian setting. Since we are operating in the Grassmann man-ifold, the usual approach which consists of minimizing the meansquare error (MSE) between the true subspace and its estimatemay not be adequate as the MSE is not the natural metric in theGrassmann manifold , i.e., the set of -dimensional subspacesin . As an al...
