Deterministic Conditions for Subspace Identifiability from Incomplete Sampling

Daniel L. Pimentel-Alarcón, Robert D. Nowak, Nigel Boston

Consider a generic $r$ -dimensional subspace of $R^{d}$ , $r < d$ , and suppose that we are only given projections of this subspace onto small subsets of the canonical coordinate…
