Joint Approximate Partial Diagonalization of Large Matrices
Abd-Krim Seghouane, Yousef Saad
Given a set of symmetric (real) matrices, the Orthogonal Joint Diagonalization (OJD) problem consists of finding an orthonormal basis in which the representation of each of the…
Find the dimension that counts: Fast dimension estimation and Krylov PCA
Shashanka Ubaru, Abd-Krim Seghouane, Yousef Saad
High dimensional data and systems with many degrees of freedom are often characterized by covariance matrices. In this paper, we consider the problem of simultaneously estimating t…
Fast estimation of approximate matrix ranks using spectral densities
Shashanka Ubaru, Yousef Saad, Abd-Krim Seghouane
In many machine learning and data related applications, it is required to have the knowledge of approximate ranks of large data matrices at hand. In this paper, we present two comp…
