Nonnegative matrix factorisation and tri-factorisation Nonnegative matrix factorisation (NMF) and tri-factorisation (NMTF) methods decompose a given matrix R into two or three smaller matrices so that R ≈ UV T or R ≈ FSG , respectively. Schmidt, Winther and Hansen (2009) introduced a Bayesian version of nonnegative matrix factorisation (left), which we extend to matrix tri-factorisation (right)...

High tempo detection accuracies have been reported for the analysis of percussive, constant-tempo, Western music audio signals. As a consequence, active research in the tempo detection domain has been shifted to yet open tasks like tempo analysis of non-percussive, expressive, or non-western music. Also, tempo detection is included in a large range of music-related software. In DJ software, fea...
Objectives: This work focuses on creating targeted content-specific topicbased clusters. They can help users to discover the topics in a set of documents information more efficiently. Methods/Statistical analysis: The Non-negative Matrix Factorization (NMF) based models learn by directly decomposing term-document matrix, which is bag-of-word matrix representation text corpus, into two low-rank ...
