Elastic nonnegative matrix factorization

Pattern Recognition, 2019
Abstract Nonnegative matrix factorization (NMF) plays a vital role in data mining and machine learning fields. Standard NMF utilizes the Frobenius norm while robust NMF uses the robust l2,1-norm to measure the quality of factorization, given the assumption of i.i.d Gaussian noise model and i.i.d Laplacian noise model, respectively.

Nonnegative matrix factorization with matrix exponentiation

2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010
Nonnegative matrix factorization (NMF) has been successfully applied to different domains as a technique able to find part-based linear representations for nonnegative data. However, when extra constraints are incorporated into NMF, simple gradient descent optimization can be inefficient for high-dimensional problems, due to the overhead to enforce the

Variational Nonnegative Matrix Factorisation

2009 IEEE 17th Signal Processing and Communications Applications Conference, 2009
We describe non-negative matrix factorisation (NMF) in a statistical framework, with a hierarchical generative model consisting of an observation and a prior component. Omitting the prior leads to standard NMF algorithms as special cases, where maximum likelihood parameter estimation is carried out via the Expectation-Maximisation (EM) algorithm ...
