Nonnegative approximations of nonnegative tensors [PDF]

open access: yes, 2009
We study the decomposition of a nonnegative tensor into a minimal sum of outer product of nonnegative vectors and the associated parsimonious naive Bayes probabilistic model.

Estimating Network Flow Length Distributions via Bayesian Nonnegative Tensor Factorization

open access: yesWireless Communications and Mobile Computing, Volume 2019, Issue 1, 2019., 2019
In this paper, we develop a framework to estimate network flow length distributions in terms of the number of packets. We model the network flow length data as a three‐way array with day‐of‐week, hour‐of‐day, and flow length as entities where we observe a count.

Tensor displays: compressive light field synthesis using multilayer displays with directional backlighting [PDF]

open access: yes, 2012
We introduce tensor displays: a family of compressive light field displays comprising all architectures employing a stack of time-multiplexed, light-attenuating layers illuminated by uniform or directional backlighting (i.e., any low-resolution light ...

Why You Go Reveals Who You Know: Disclosing Social Relationship by Cooccurrence

open access: yesWireless Communications and Mobile Computing, Volume 2017, Issue 1, 2017., 2017
The popularity of location‐based services (LBS) and the ubiquity of sensor device have resulted in rich spatiotemporal data. A large number of human behaviors had been recorded including cooccurrence which refers to the phenomenon that two people have been to the same places at the same time.

Neutron Flux Monitoring Based on Blind Source Separation Algorithms in Moroccan TRIGA MARK II Reactor

open access: yesScience and Technology of Nuclear Installations, Volume 2017, Issue 1, 2017., 2017
We present an overview of fission chamber’s functioning modes, theoretical aspects of the nonnegative matrix factorization methods, and the opportunities that offer neutron data processing in order to achieve neutron flux monitoring tasks. Indeed, it is a part of research project that aimed at applying Blind Source Separation methods for in‐core and ex‐

Two‐stage blind audio source counting and separation of stereo instantaneous mixtures using Bayesian tensor factorisation

open access: yesIET Signal Processing, Volume 9, Issue 8, Page 587-595, October 2015., 2015
In this paper, the authors address the tasks of audio source counting and separation for two‐channel instantaneous mixtures. This goal is achieved in two steps. First, a novel scheme is proposed for estimating the number of sources and the corresponding channel intensity difference (CID) values.

Estimating the outcome of spreading processes on networks with incomplete information: a mesoscale approach [PDF]

open access: yes, 2017
Recent advances in data collection have facilitated the access to time-resolved human proximity data that can conveniently be represented as temporal networks of contacts between individuals.

Facial Expression Recognition Based on Discriminant Neighborhood Preserving Nonnegative Tensor Factorization and ELM

open access: yesMathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014
A novel facial expression recognition algorithm based on discriminant neighborhood preserving nonnegative tensor factorization (DNPNTF) and extreme learning machine (ELM) is proposed. A discriminant constraint is adopted according to the manifold learning and graph embedding theory. The constraint is useful to exploit the spatial neighborhood structure

Computing the polyadic decomposition of nonnegative third order tensors [PDF]

open access: yes, 2011
International audienceComputing the minimal polyadic decomposition (also often referred to as canonical decomposition, or sometimes Parafac) amounts to finding the global minimum of a coercive polynomial in many variables.
