Nonlocal Low-Rank Nonnegative Tensor Factorization for Hyperspectral Unmixing
Hyperspectral unmixing decomposes hyperspectral images (HSI) into a collection of constituent materials or end-members and their fractions, i.e., abundances. Nonnegative tensor factorization (NTF) has been utilized thanks to its ability of preserving all

Non-negative tensor factorization with applications to statistics and computer vision [PDF]
We derive algorithms for finding a nonnegative n-dimensional tensor factorization (n-NTF) which includes the non-negative matrix factorization (NMF) as a particular case when n = 2.

Superpixel-Based Nonnegative Tensor Factorization for Hyperspectral Unmixing
Hyperspectral unmixing aims at decomposing a hyperspectral image (HSI) into a number of constituted materials and associated proportions. Recently, nonnegative tensor factorization (NTF) based methods have been proved effective and natural for ...

Sparse image coding using a 3D non-negative tensor factorization [PDF]
We introduce an algorithm for a non-negative 3D tensor factorization for the purpose of establishing a local parts feature decomposition from an object class of images. In the past such a decomposition was obtained using nonnegative matrix factorization (

Nonnegative tensor factorization for continuous EEG classification
In this paper we present a method for continuous EEG classification, where we employ nonnegative tensor factorization (NTF) to determine discriminative spectral features and use the Viterbi algorithm to continuously classify multiple mental tasks.
