The R package vrnmf implements a set of methods to perform non-negative matrix decomposition with minimum volume constraints. A general problem is to decompose a non-negative matrix in a product of ...
Abstract: This letter proposes a fast yet efficient method to solve the hyperspectral (HS) unmixing problem in the challenging unsupervised context, i.e., when the endmember spectral signatures are ...
General Semi-Nonnegative Matrix Factorization and Its Application for Statistical Process Monitoring
Abstract: As an effective feature extraction and dimensionality reduction technique, nonnegative matrix factorization (NMF) has been widely applied in fault detection in recent years. The requirement ...
On Jan. 10, Chinese scientists uploaded the genetic sequence of a novel coronavirus, later named SARS-CoV-2, to an open-access website, GenBank. The virus had been linked to a growing number of ...
