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 ...
在数学公式、定理或算法中,例如「非负矩阵分解」(Non-negative Matrix Factorization)、「非负约束优化」(Non-negative Constrained Optimization),均使用「非负的」强调数值的允许范围。 工程与计算机科学 数据科学中的特征值、概率统计中的概率密度函数等场景,需明确排除负值,此时「非负...
NMF (Nonnegative Matrix Factorization)In this study, we deal with the neutron flux monitoring inside the TRIGA MARK II reactor as one of the nonnegative matrix factorization problems. The fact that these methods of separating blind sources does not require any assumptions on the way the signal ...

Recently, nonnegative matrix factorization (NMF) has been widely adopted for community detection, because of its better interpretability. However, the existing NMF-based methods have the following three problems: 1. they directly transform the original network into community membership space, so it is...
