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…

Sensing with Optimal Matrices
Hema Kumari Achanta, Soura Dasgupta, Weiyu Xu
We consider the problem of designing optimal () sensing matrices which minimize the maximum condition number of all the submatrices of columns. Such matr…
