TL;DR
通过将可分离性非负矩阵因式分解问题转化为寻找一个向量有限集的锥壳的极端射线，本文提出了一类高度可扩展和实验噪声稳健的新型可分离 NMF 算法，并实现了分布式共享内存的高可扩展性算法
Abstract
The
separability assumption
(Donoho & Stodden, 2003; Arora et al., 2012) turns
non-negative matrix factorization
(NMF) into a tractable problem. Recently, a new class of provably-correct NMF algorithms have emerg
