WebDetecting genomes with similar expression patterns using clustering techniques plays an important role in gene expression data analysis. Non-negative matrix factorization (NMF) is an effective method for clustering the analysis of gene expression data. However, the NMF-based method is performed within the Euclidean space, and it is usually … WebJul 26, 2024 · 2.2 Graph regularized nonnegative matrix factorization (GNMF). NMF does not make use of the inherent local geometry information of the data. By introducing a manifold regularization term, Cai et al.
