Efficient and Robust Compressed Sensing using High-Quality Expander Graphs
Sina Jafarpour, Weiyu Xu, Babak Hassibi +1
Expander graphs have been recently proposed to construct efficient compressed sensing algorithms. In particular, it has been shown that any -dimensional vector that is -spars…

Robust Dimension Reduction, Fusion Frames, and Grassmannian Packings
Gitta Kutyniok, Ali Pezeshki, Robert Calderbank +1
We consider estimating a random vector from its noisy projections onto low dimensional subspaces constituting a fusion frame. A fusion frame is a collection of subspaces, for which…
