Acceleration of Randomized Kaczmarz Method via the Johnson-Lindenstrauss Lemma
Yonina C. Eldar, Deanna Needell
The Kaczmarz method is an algorithm for finding the solution to an overdetermined consistent system of linear equations Ax=b by iteratively projecting onto the solution spaces. The…
Compressed Sensing with Coherent and Redundant Dictionaries
Emmanuel J. Candes, Yonina C. Eldar, Deanna Needell +1
This article presents novel results concerning the recovery of signals from undersampled data in the common situation where such signals are not sparse in an orthonormal basis or i…
Mixed Operators in Compressed Sensing
Matthew A. Herman, Deanna Needell
Applications of compressed sensing motivate the possibility of using different operators to encode and decode a signal of interest. Since it is clear that the operators cannot be t…
