Positive tensor factorization

Pattern Recognition Letters, 2001
Summary: A novel fixed point algorithm for Positive Tensor Factorization (PTF) is introduced. The update rules efficiently minimize the reconstruction error of a positive tensor over positive factors. Tensors of arbitrary order can be factorized, which extends earlier results in the literature.

A faster tensor robust PCA via tensor factorization

International Journal of Machine Learning and Cybernetics, 2020
Many kinds of real-world multi-way signal, like color images, videos, etc., are represented in tensor form and may often be corrupted by outliers. To recover an unknown signal tensor corrupted by outliers, tensor robust principal component analysis (TRPCA) serves as a robust tensorial modification of the fundamental PCA.

Factorized Tensor Dictionary Learning for Visual Tensor Data Completion

IEEE Transactions on Multimedia, 2021
This paper aims at developing a dictionary-learning-based method for completing the visual tensor data with missing elements. Traditional dictionary learning approaches suffer from very high computational costs when processing high-dimensional tensor data.

Coupled graph tensor factorization

2016 50th Asilomar Conference on Signals, Systems and Computers, 2016
Factorization of a single matrix or tensor has been used widely to reveal interpretable factors or predict missing data. However, in many cases side information may be available, such as social network activities and user demographic data together with Netflix data.

Transit Pattern Detection Using Tensor Factorization

INFORMS Journal on Computing, 2019
Understanding citywide transit patterns is important for transportation management, including city planning and route optimization. The wide deployment of automated fare collection (AFC) systems in public transit vehicles has enabled us to collect massive amounts of transit records, which capture passengers’ traveling activities. Based on such transit

UNBRAIDING TRANSFORMATIONS FOR BRAIDED TENSOR FACTORS

Modern Physics Letters A, 2001
Two quantum group covariant algebras [Formula: see text] can be embedded in a larger one through the so-called braided tensor product, whereby they do not commute with each other. We briefly report on our transformations of generators8 which allow to express this braided tensor product algebra as an ordinary tensor product algebra of [Formula: see ...

Probabilistic Latent Tensor Factorization

2010
We develop a probabilistic framework for multiway analysis of high dimensional datasets. By exploiting a link between graphical models and tensor factorization models we can realize any arbitrary tensor factorization structure, and many popular models such as CP or TUCKER models with Euclidean error and their non-negative variants with KL error appear ...

Tensor Independent Component Analysis and Tensor Non-Negative Factorization

2009
In this chapter, we describe two tensor-based subspace analysis approaches (tensor ICA and tensor NMF) that can be used in many fields like face recognition and other biometric recognition. Section 10.1 gives the background and development of the two tensor-based subspace analysis approaches.
