Note Onset Detection via Nonnegative Factorization of Magnitude Spectrum

EURASIP Journal on Advances in Signal Processing, 2008
A novel approach for onset detection of musical notes from audio signals is presented. In contrast to most commonly used conventional approaches, the proposed method features new detection functions constructed from the linear temporal bases that are ...

Determining Patterns in Neural Activity for Reaching Movements Using Nonnegative Matrix Factorization

EURASIP Journal on Advances in Signal Processing, 2005
We propose the use of nonnegative matrix factorization (NMF) as a model-independent methodology to analyze neural activity. We demonstrate that, using this technique, it is possible to identify local spatiotemporal patterns of neural activity in the ...
