Shifted NMF with Group Sparsity for Clustering NMF Basis Functions [PDF]
Recently, Non-negative Matrix Factorisation (NMF) has found application in separation of individual sound sources. NMF decomposes the spectrogram of an audio mixture into an additive parts based representation where the parts typically correspond to ...

GSVD-NMF: Recovering Missing Features in Non-negative Matrix Factorization [PDF]
Non-negative matrix factorization (NMF) is an important tool in signal processing and widely used to separate mixed sources into their components. Algorithms for NMF require that the user choose the number of components in advance, and if the results are

Generalized Alpha-Beta Divergences and Their Application to Robust Nonnegative Matrix Factorization
We propose a class of multiplicative algorithms for Nonnegative Matrix Factorization (NMF) which are robust with respect to noise and outliers. To achieve this, we formulate a new family generalized divergences referred to as the Alpha-Beta-divergences ...

Research on Human Face Recognition Based on Improved NMF Algorithm
研究人脸识别是为了提高身份识别的明确性,具有直接、友好、方便等优点。但传统的基于PCA的人脸识别算法易受光照、表情、姿态等因素的干扰,从而导致其识别率的下降;鉴于此,提出了改进的NMF(非负矩阵分解)人脸图像识别算法。通过在NMF算法嵌入基于多超图的流形学习算法,可以在人脸图像的降维过程中最优地保持各图像间的流形信息,从而实现人脸识别算法对光照、表情、姿态等因素的鲁棒性。另外,为降低运算成本,提出了在测试阶段采用增量式的迭代求解算法。在人脸数据库ORL、YALE上进行试验的结果表明 ...
