Optimal Approximation of Elliptic Problems by Linear and Nonlinear Mappings
We study the optimal approximation of the solution of an operator equation A(u) = f by four types of mappings: a) linear mappings of rank n; b) n-term approximation with respect t...

On the Set of Images Modulo Viewpoint and Contrast Changes
We consider regions of images that exhibit smooth statistics, and pose the question of characterizing the “essence” of these regions that matters for visual recognition. Ideal...
