Construction et simulation graphiques de comportements : le modèle des Icobjs

Intuitively, a graphical simulation (virtual world, game,...) can be seen as a finite space inwhich several entities, each having its own behavior, evolve in parallel. So it seems natural touse concurrent languages to program those behaviors. However, it is seldom the case due to thecomplexity of programming and debugging them, because they introduce non-determinismand are ineff...

Colinearité et Instabilité Numérique dans le Modèle Linéaire

In this paper we give the expression of the multiple corrélation coefficient in a linear model according to the coefficients of corrélation. This expression makes it possible to analyze from a numerical point ofview the instability of estimâtes in the case of collinear explanatory variables in the linear model or in the autoregressive model. This numerical approach, thaï we show on two examples...

Représentation de connaissances descriptives et classificatoires : le modèle CoDesc

To meet the needs of biologists wishing to have representation models and knowledge management tools adapted to their scientific method, we propose an object-oriented model, CoDesc, allowing them to represent descriptive and classifying knowledge. An entity of higher level than the class, the descriptive model, is used to represent the concepts of the real world. The properties of the descripti...

Habitude et principe de compatibilité dans le modèle du comportement planifié : décisions pro-environnementales et automobile

Modèle de langue visuel pour la reconnaissance de scènes

We describe here a method to use a graph language modeling approach for image retrieval and image categorization. Since photographic images are 2D data, we first use image regions (mapped to automatically induced concepts) and then spatial relationships between these regions to build a complete image graph representation. Our method deals with different scenarios, where isolated images or group...
