On trivial solution and scale transfer problems in graph regularized NMF
TL;DR: A Normalized Cut-like constraint is imposed on the cluster assignment matrix to make the optimization problem well-defined, and a multiplicative updating algorithm is derived that can be applied for document clustering and co-clustering respectively.

Editorial: Music genre classification based on local feature selection using a self-adaptive harmony search algorithm
TL;DR: An automatic music genre-classification system based on a local feature-selection strategy by using a self-adaptive harmony search (SAHS) algorithm that shows that the local-selection strategies using wrapper and filter approaches ranked first and third in performance among all relevant methods.
Journal ArticleDOI
Local Coordinate Concept Factorization for Image Representation
TL;DR: A locality constraint is introduced into the traditional CF by requiring the concepts (basis vectors) to be as close to the original data points as possible, each datum can be represented by a linear combination of only a few basis concepts.

Network-wide Crowd Flow Prediction of Sydney Trains via Customized Online Non-negative Matrix Factorization
TL;DR: Intensive experiments on a large-scale, real-world dataset containing transactional data demonstrate the superiority of the proposed three online non-negative matrix factorization (ONMF) models.

Single-channel source separation using simplified-training complex matrix factorization
Brian King,Les Atlas +1 more
TL;DR: A new method of creating learned sets of bases used in the matrix factorization technique for single-channel source separation, which does not suffer the complication of choosing an optimal number of bases as in previous methods is presented.
