内容摘要:

Nonnegative matrix factorization (NMF) is one of the most powerful dimensionality reduction techniques for the analysis of high-dimensional data, and it has been successfully used in the fields of machine learning and data mining due to the simplicity and intuitive decomposition. The past decade has witnessed a rapid development of the NMF techniques, which develops many new NMF methods to solve different practical issues. However, traditional NMF methods still suffer from the data with non-Gaussian noise and outliers, and fail to make full use of limited supervised information for improving the performance of the NMF methods. In recent years, the information theoretical learning and semi-supervised learning techniques have been incorporated into NMF model to overcome the above mentioned problems.

Some novel robust and semi-supervised NMF methods will be introduced.
