Why Gabor Frames? Two Fundamental Measures of Coherence and Their Role in Model Selection
Waheed U. Bajwa, Robert Calderbank, Sina Jafarpour
This paper studies non-asymptotic model selection for the general case of arbitrary design matrices and arbitrary nonzero entries of the signal. In this regard, it generalizes the…
Performance bounds for expander-based compressed sensing in Poisson noise
Maxim Raginsky, Sina Jafarpour, Zachary Harmany +3
This paper provides performance bounds for compressed sensing in the presence of Poisson noise using expander graphs. The Poisson noise model is appropriate for a variety of applic…
Sparse Reconstruction via The Reed-Muller Sieve
Robert Calderbank, Stephen Howard, Sina Jafarpour
This paper introduces the Reed Muller Sieve, a deterministic measurement matrix for compressed sensing. The columns of this matrix are obtained by exponentiating codewords in the q…
Fishing in Poisson streams: focusing on the whales, ignoring the minnows
Maxim Raginsky, Sina Jafarpour, Rebecca Willett +1
This paper describes a low-complexity approach for reconstructing average packet arrival rates and instantaneous packet counts at a router in a communication network, where the arr…
