A Dimension Reduction Scheme for the Computation of Optimal Unions of Subspaces
Given a set of points F in a high dimensional space, the problem of finding a union of subspaces ∪i Vi ⊆ RN that best explains the data F increases dramatically with the dimension of RN. In this article, we study...

Sampling in a Union of Frame Generated Subspaces
A new paradigm in sampling theory has been developed recently by Lu and Do. In this new approach the classical linear model is replaced by a non-linear, but structured, model consisting of a union of subspaces...
