非负矩阵分解是一种矩阵分解技术,它将一个非负矩阵V分解为两个低维非负矩阵W和H的乘积,即V≈ WH。其中,V是原始数据矩阵,W是基础矩阵(或特征矩阵),H是系数矩阵(或权重矩阵)。NMF要求分解后的所有元素均为非负,这符合许多实际问题的物理意义(如像素值、文档词频等)。
A novel algorithm, stretchedNMF, is introduced for non-negative matrix factorization (NMF), accounting for signal stretching along the independent variable’s axis. It addresses signal variability caused by stretching, proving beneficial for analyzing data such as powder diffraction at varying temperatures...
We further argue Nonnegative Matrix Factorization (NMF) is an especially promising linear decomposition method for analysis of activity recorded in calcium imaging in this context. NMF operates under the constraint that every element in the data, and the decomposition, be nonnegative41, as is ...
Nonnegative matrix factorization (NMF) is widely used to analyze high-dimensional count data because, in contrast to real-valued alternatives such as factor analysis, it produces an interpretable parts-based representation. However, in applications such as spatial transcriptomics, NMF fails to incorporat...
