摘要翻译：
非负矩阵分解(NMF)因其模型的简洁性和可解释性而成为信号和数据分析的主要工具。也许有点令人惊讶的是，直到最近几年，人们对其模型的可识别性--在许多应用中，如主题挖掘和高光谱成像的可解释性背后的主要原因--的理解一直相当有限。从2010年代开始，NMF的可识别性研究取得了长足的进展：信号处理(SP)和机器学习(ML)界发现了许多有趣而重要的结果。NMF的可辨识性在实践中对许多方面都有很大的影响，如避免不适定公式和保证性能的算法设计。另一方面，没有教程论文从可识别性的观点介绍NMF。本文旨在填补这一空白，对NMF的模型可辨识性及其与算法和应用的联系进行全面而深入的介绍。本教程将帮助研究人员和研究生掌握NMF的本质和见解，从而避免经常由于无法识别的NMF配方而出现的典型“陷阱”。本文还将帮助实践者为自己的问题挑选/设计合适的因式分解工具。

英文摘要：
  Nonnegative matrix factorization (NMF) has become a workhorse for signal and data analytics, triggered by its model parsimony and interpretability. Perhaps a bit surprisingly, the understanding to its model identifiability---the major reason behind the interpretability in many applications such as topic mining and hyperspectral imaging---had been rather limited until recent years. Beginning from the 2010s, the identifiability research of NMF has progressed considerably: Many interesting and important results have been discovered by the signal processing (SP) and machine learning (ML) communities. NMF identifiability has a great impact on many aspects in practice, such as ill-posed formulation avoidance and performance-guaranteed algorithm design. On the other hand, there is no tutorial paper that introduces NMF from an identifiability viewpoint. In this paper, we aim at filling this gap by offering a comprehensive and deep tutorial on model identifiability of NMF as well as the connections to algorithms and applications. This tutorial will help researchers and graduate students grasp the essence and insights of NMF, thereby avoiding typical `pitfalls' that are often times due to unidentifiable NMF formulations. This paper will also help practitioners pick/design suitable factorization tools for their own problems.
