Automated transport separation using the neural shifted proper orthogonal decomposition
Beata Zorawski, Shubhaditya Burela, Philipp Krah +2
This paper presents a neural network-based methodology for the decomposition of transport-dominated fields using the shifted proper orthogonal decomposition (sPOD). Classical sPOD…
Majorization-minimization for Sparse Nonnegative Matrix Factorization with the -divergence
Arthur Marmin, José Henrique de Morais Goulart, Cédric Févotte
This article introduces new multiplicative updates for nonnegative matrix factorization with the -divergence and sparse regularization of one of the two factors (say, the activa…
Joint Majorization-Minimization for Nonnegative Matrix Factorization with the -divergence
Arthur Marmin, José Henrique de Morais Goulart, Cédric Févotte
This article proposes new multiplicative updates for nonnegative matrix factorization (NMF) with the -divergence objective function. Our new updates are derived from a joint maj…
