An iterative Jacobi-like algorithm to compute a few sparse approximate eigenvectors
Cristian Rusu
In this paper, we describe a new algorithm that approximates the extreme eigenvalue/eigenvector pairs of a symmetric matrix. The proposed algorithm can be viewed as an extension of…

A Note on Shift Retrieval Problems
Cristian Rusu
In this note, we discuss the shift retrieval problems, both classical and compressed, and provide connections between them using circulant matrices. We review the properties of cir…
