RJD-BASE: Multi-Modal Spectral Clustering via Randomized Joint Diagonalization

Haoze He, Artemis Pados, Daniel Kressner

We revisit the problem of spectral clustering in multimodal settings, where each data modality is encoded as a graph Laplacian. While classical approaches--including joint diagonal…

On the randomized SVD in infinite dimensions

Daniel Kressner, David Persson, André Uschmajew

Randomized methods, such as the randomized SVD (singular value decomposition) and Nyström approximation, are an effective way to compute low-rank approximations of large matrices.…

Compression Properties for large Toeplitz-like matrices

Bernhard Beckermann, Daniel Kressner, Heather Wilber

Toeplitz matrices are abundant in computational mathematics, and there is a rich literature on the development of fast and superfast algorithms for solving linear systems involving…
