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…

Fast approximation of orthogonal matrices and application to PCA
Cristian Rusu, Lorenzo Rosasco
We study the problem of approximating orthogonal matrices so that their application is numerically fast and yet accurate. We find an approximation by solving an optimization proble…

Approximate Eigenvalue Decompositions of Linear Transformations with a Few Householder Reflectors
Cristian Rusu
The ability to decompose a signal in an orthonormal basis (a set of orthogonal components, each normalized to have unit length) using a fast numerical procedure rests at the heart…
