Ordonnancement d'entités pour la rencontre du web des documents et du web des données

The advances of the Linked Open Data (LOD) initiative are giving rise to a more structured web of data. A few datasets act as hubs (e.g., DBpedia) connecting many other datasets. They also make possible new web services for entity detection inside plain text (e.g., DBpedia Spotlight), thus allowing for new applications that will benefit from a combination of the web of documents and the web of ...

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...

Analyse en relativité d'échelle du bassin versant du Gardon (Gard, France). Étude de la variation de la dimension fractale en fonction de l'altitude et de l'échelle

Level curves higher than 100 m of the Gardon basin are analysed using scale relativity tools. These curves depend explicitly on scale (box counting method) and altitude. This dependence is solution of a partial derivative equation (in terms of scale and position). Then the descriptions in terms of scale invariance (constant fractal dimension DF ) are generalized to scale covariance (variable DF...
