Linear Inverse Problems with Norm and Sparsity Constraints
Volkan Cevher, Sina Jafarpour, Anastasios Kyrillidis
We describe two nonconventional algorithms for linear regression, called GAME and CLASH. The salient characteristics of these approaches is that they exploit the convex -ba…
Quasi-Optimal Network Utility Maximization for Scalable Video Streaming
Mohammad Sadegh Talebi, Ahmad Khonsari, Mohammad Hassan Hajiesmaili +1
This paper addresses rate control for transmission of scalable video streams via Network Utility Maximization (NUM) formulation. Due to stringent QoS requirements of video streams…
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…
Reed Muller Sensing Matrices and the LASSO
Robert Calderbank, Sina Jafarpour
We construct two families of deterministic sensing matrices where the columns are obtained by exponentiating codewords in the quaternary Delsarte-Goethals code . This meth…
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…
