Semi-Supervised Nonnegative Matrix Factorization

, 2018
Nonnegative matrix factorization (NMF) is a popular method for low-rank approximation of nonnegative matrix, providing a useful tool for representation learning that is valuable for clustering and classification.

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 ...

Sparse Separable Nonnegative Matrix Factorization

, 2020
International audienceWe propose a new variant of nonnegative matrix factorization (NMF), combining separability and sparsity assumptions. Separability requires that the columns of the first NMF factor are equal to columns of the input matrix, while ...
