Union of subspaces, manifold-modeled signals, and differential geometry interpretation

Notions of a union of subspaces and manifold-modeled signals play key roles in modern signal processing. In this paper, we explore the differential geometry structures of these signal spaces. To this end, a sparse generalized Prony signal model is used as a toy model. We show that the family of K-dimensional generalize...
