Two step recovery of jointly sparse and low-rank matrices: theoretical guarantees

5 Dec 2014Sampurna BiswasSunrita PoddarSoura DasguptaRaghuraman MudumbaiMathews Jacob

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 estimates the row subspace of the matrix using a set of common measurements of the columns... (read more)
