Multichannel Nonnegative Matrix Factorization in Convolutive Mixtures for Audio Source Separation
Abstract--We consider inference in a general data-driven object-based model of multichannel audio data, assumed generated as a possibly underdetermined convolutive mixture of sourc...

Perturbed Hidden Matrix Cryptosystems
Abstract. We apply internal perturbation [3] to the matrix-type cryptosystems [Cn] and HM constructed in [9]. Using small instances of these variants, we investigate the existence ...

Summarizing video using non-negative similarity matrix factorization
Abstract— We present a novel approach to automatically extracting summary excerpts from audio and video. Our approach is to maximize the average similarity between the excerpt an...

Matrix interpretation of multiple orthogonality
Abstract: In this work we give an interpretation of a (s(d + 1) + 1)-term recurrence relation in terms of type II multiple orthogonal polynomials. We rewrite this recurrence relati...
