The Fast Slepian Transform
Santhosh Karnik, Zhihui Zhu, Michael B. Wakin +2
The discrete prolate spheroidal sequences (DPSS's) provide an efficient representation for discrete signals that are perfectly timelimited and nearly bandlimited. Due to the high c…
Computing Active Subspaces Efficiently with Gradient Sketching
Paul G. Constantine, Armin Eftekhari, Michael B. Wakin
Active subspaces are an emerging set of tools for identifying and exploiting the most important directions in the space of a computer simulation's input parameters; these direction…
Analysis of Orthogonal Matching Pursuit using the Restricted Isometry Property
Mark A. Davenport, Michael B. Wakin
Orthogonal Matching Pursuit (OMP) is the canonical greedy algorithm for sparse approximation. In this paper we demonstrate that the restricted isometry property (RIP) can be used f…
