Nonnegative 3-way tensor factorization via conjugate gradient with globally optimal stepsize [PDF]

open access: yes, 2011
International audienceThis paper deals with the minimal polyadic decomposition (also known as canonical decomposition or Parafac) of a 3-way array, assuming each entry is positive. In this case, the low-rank approximation problem becomes well-posed.

Extraction of Temporal Network Structures from Graph-based Signals [PDF]

open access: yes, 2016
International audienceA new framework to track the structure of temporal networks with a signal processing approach is introduced. The method is based on the duality between static networks and signals, obtained using a multidimensional scaling technique,

A tensor analysis improved genetic algorithm for online bin packing [PDF]

open access: yes, 2015
Mutation in a Genetic Algorithm is the key variation operator adjusting the genetic diversity in a population throughout the evolutionary process. Often, a fixed mutation probability is used to perturb the value of a gene.

Music genre classification: a multilinear approach [PDF]

open access: yes, 2008
In this paper, music genre classification is addressed in a multilinear perspective. Inspired by a model of auditory cortical processing, multiscale spectro-temporal modulation features are extracted.

Anomaly detection in temporal graph data: An iterative tensor decomposition and masking approach [PDF]

open access: yes, 2015
Sensors and Internet-of-Things scenarios promise a wealth of interaction data that can be naturally represented by means of timevarying graphs. This brings forth new challenges for the identification and removal of temporal graph anomalies that entail ...

A multilevel approach for nonnegative matrix factorization [PDF]

open access: yes
Nonnegative Matrix Factorization (NMF) is the problem of approximating a nonnegative matrix with the product of two low-rank nonnegative matrices and has been shown to be particularly useful in many applications, e.g., in text mining, image processing ...
