Subspace based low rank and joint sparse matrix recovery
Sampurna Biswas, Sunrita Poddar, Soura Dasgupta +2
We consider the recovery of a low rank and jointly sparse matrix from under sampled measurements of its columns. This problem is highly relevant in the recovery of dynamic MRI data…

Two step recovery of jointly sparse and low-rank matrices: theoretical guarantees
Sampurna Biswas, Sunrita Poddar, Soura Dasgupta +2
We introduce a two step algorithm with theoretical guarantees to recover a jointly sparse and low-rank matrix from undersampled measurements of its columns. The algorithm first est…
