From: bioNMF: a versatile tool for non-negative matrix factorization in biology
Main bioNMF window. The tool is divided into three main functional modules: data input, data transformation and analysis modules (standard NMF, bicluster analysis and sample classification). Standard NMF implements the classical Lee and Seung NMF algorithm. Bicluster analysis uses a sparse variant of the NMF model while Sample classification implements an unsupervised classification method that uses NMF to classify experimental samples.
