  • AUTOMATIC GATHERING STRATEGY FOR UNSUPERVISED SOURCE SEPARATION ALGORITHMS
    Publication number: 20100138010
    Abstract: Unsupervised learning algorithms for audio source separation such as non-negative matrix factorization (NMF) and principal components analysis (PCA) can be understood as a data matrix factorization subject to different constraints. These algorithms provide components with a relevant structure and homogeneous musical events. The invention presents an automatic fusion method to merge these components into tracks associated to the different instruments present in the sound source.
