Smoothed Analysis of Tensor Decompositions [PDF]

open access: yesProceedings of the forty-sixth annual ACM symposium on Theory of computing, 2014
Low rank tensor decompositions are a powerful tool for learning generative models, and uniqueness results give them a significant advantage over matrix decomposition methods. However, tensors pose significant algorithmic challenges and tensors analogs of

Spectral tensor-train decomposition [PDF]

open access: yesSIAM Journal on Scientific Computing, 2015
The accurate approximation of high-dimensional functions is an essential task in uncertainty quantification and many other fields. We propose a new function approximation scheme based on a spectral extension of the tensor-train (TT) decomposition.

Clustering Patients with Tensor Decomposition [PDF]

open access: yesCoRR, 2017
In this paper we present a method for the unsupervised clustering of high-dimensional binary data, with a special focus on electronic healthcare records. We present a robust and efficient heuristic to face this problem using tensor decomposition.

Hermitian Tensor Decompositions [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 2020
Hermitian tensors are generalizations of Hermitian matrices, but they have very different properties. Every complex Hermitian tensor is a sum of complex Hermitian rank-1 tensors. However, this is not true for the real case. We study basic properties for Hermitian tensors such as Hermitian decompositions and Hermitian ranks. For canonical basis tensors,

Counting Tensor Rank Decompositions [PDF]

open access: yesUniverse, 2021
Tensor rank decomposition is a useful tool for geometric interpretation of the tensors in the canonical tensor model (CTM) of quantum gravity. In order to understand the stability of this interpretation, it is important to be able to estimate how many tensor rank decompositions can approximate a given tensor.

Multi-Modal Image Fusion Based on Matrix Product State of Tensor

open access: yesFrontiers in Neurorobotics, 2021
Multi-modal image fusion integrates different images of the same scene collected by different sensors into one image, making the fused image recognizable by the computer and perceived by human vision easily.

Orthogonal decomposition of tensor trains [PDF]

open access: yesLinear and Multilinear Algebra, 2021
In this paper we study the problem of decomposing a given tensor into a tensor train such that the tensors at the vertices are orthogonally decomposable. When the tensor train has length two, and the orthogonally decomposable tensors at the two vertices are symmetric, we recover the decomposition by considering random linear combinations of slices ...
