摘要

在本文中，我们证明了PLSI和NMF优化相同的目标函数，尽管PLSI和NMF是不同的算法，并通过实验验证。此外，我们还提出了一种新的混合方法，即交替运行PLSI和NMF以获得更好的解决方案。

NMF and PLSI: equivalence and a hybrid algorithm

In this paper, we show that PLSI and NMF optimize the same objective function, although PLSI and NMF are different algorithms as verified by experiments. In addition, we also propose a new hybrid method that runs PLSI and NMF alternatively to achieve better solutions.
