On the Power of Adaptivity in Sparse Recovery
The goal of (stable) sparse recovery is to recover a k-sparse approximation x* of a vector x from linear measurements of x. Specifically, the goal is to recover x* such that ∥x-x*∥[subscript p] ≤ C min, k-sparse x, ∥x-x'∥[subscript q] for some constant C and norm parameters p and q. It is known...
