5. major contribution: unification of uncertainty theories  a number of formal descriptions of uncertainty have been proposed:  probabilities, possibilities, fuzzy sets, random sets, monotone capacities, inner measures  I formulated a geometric approach to uncertainty theories, which unifies additive and non-additive measures  how to arrange them in a single, unified framework?  Fabio Cuzzolin, “Geometry of Dempster's rule of combination”, IEEE Transactions on Systems, Man, and Cybernetics part B, 34(2), pages 961- 977, April 2004  Fabio Cuzzolin, “Two new Bayesian approximations of belief functions based on convex geometry”, IEEE Transactions on Systems, Man, and Cybernetics part B, 37(4), August 2007  Fabio Cuzzolin, “A geometric approach to the theory of evidence”, IEEE Transactions on Systems, Man, and Cybernetics part C, 2007 (to appear)

6. P geometric approach uncertainty measures can be represented as points of a simplex! approximating belief functions with probabilities or fuzzy sets b P(b) P(b’) b’ b f p working with belief functions is working with convex sets of probs

7. another example: spectral matching central problem in vision (and not only): matching But then they map articulated bodies into a stable shape nonlinear embeddings (LLE,ISOMAP) map a dataset onto an embedding space while preserving local structure or geodesic distances

8. graph matching spectral matching they can then be used to match dense shapes by simply aligning their images after embedding!  Fabio Cuzzolin, Diana Mateus, Edmond Boyer, and Radu Horaud, “Robust spectral 3D-bodypart segmentation in time”, submitted to the International Conference on Computer Vision (ICCV 2007), Rio de Janeiro, April 10 2007  Diana Mateus, Fabio Cuzzolin, Edmond Boyer, and Radu Horaud, “Articulated Shape Matching by Robust Alignment of Their Embedded Representations”, submitted to ICCV2007, Rio de Janeiro, 2007  Fabio Cuzzolin, “Learning Riemannian Metrics for Classification of Dynamical Models”, submitted to the International Conference on Computer Vision (ICCV 2007), Rio de Janeiro, April 10 2007 protein analysis motion capture bodypart segmentation

Contributions to Vista and the Unité de Recherche on the methodologies: new expertise in fields like: non-Bayesian theories spectral methods discrete math sensor fusion under uncertainty on the problems: familiarity with applications like surveillance and identity recognition context-aware applications (event detection, gesture analysis) possible new directions: smart rooms, driver’s behavior networking: links with groups in computer vision, statistics, machine learning imprecise probabilities, graph theory
