-Orange NMF is an add-on for Orange_ data mining software package.
-Orange is open source, data mining software based on Python and C++
-programming. A useful component of Orange allows for a drag and drop interface to
-visualize building the data processing flow and analysis pipeline, or visual programming.
-On the canvas of this modular program, analysis or processing objects called “widgets”
-are dropped and connected to create a simple yet powerful data processing flow.
-In this project, the Orange-NMF add on makes two popular matrix factorization methods available in Orange; non-negative
-matrix factorization (NMF), and robust singular value decomposition, (rSVD).
-To support these matrix factorization widgets, pre- and
-post- data processing widgets are included in the module. The pre-processing widgets
-are designed to deal with normalizations, missing data, etc. The post-processing
