Dimension reduction via Diffusion maps

The presentation will take place on Zoom.

Abstract: The Curse of Dimensionality is a common issue in data analysis. A dimension reduction approach using the techniques of diffusion maps has been considered in the case of the Riemannian manifold of symmetric positive definite(SPD) matrices. A brief description of the diffusion techniques, of the geometry of the SPD manifold, and of numerical experiments involving classification of textures represented by region covariance matrices will given in the presentation.
