Webb2.2 Semi-NMF ([22]) Semi-NMF is designed for the data matrix X that has mixed signs. In semi-NMF, G is restricted to be nonnegative while the other factor matrix F can have mixed signs, i.e., semi-NMF can take the following form2: X± ≈ F±GT +. This model is motivated from the perspective of data clustering. When clustering the columns WebbTo characterize the intratumor heterogeneity of neoplastic cells, we analyzed clusters of coexpressed genes in each tumor based on nonnegative matrix factorization (NMF) and obtained a total of 25 intratumor signatures (table S3). Taking ACP-3 as an example, the NMF results demonstrated complex intratumoral expression features in ACP . breakfast saint john nb
