Orange NMF is an add-on for Orange data mining software package. It provides non-negative matrix factorization algorithms (NMF) through NIMFA and robust singular value decomposition (rSVD). it includes pre- and post-data processing widgets. The pre-processing widgets are designed to deal with normalizations, missing data, etc. The post-processing widgets are designed to view and assess the results of matrix factorization.
Documentation is found at:
Widgets were desgined by Fajwel Fogel (Ecole Polytechnique ParisTech). All the NMF methods call NIMFA library, implemented by Marinka Zitnik (Bioinformatics Laboratory, FRI UL).
