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 much of the matrix algebra toolkit are unlikely to exist because of hardness results.

Randomized CP tensor decomposition

open access: yesMachine Learning: Science and Technology, 2020
Abstract The CANDECOMP/PARAFAC (CP) tensor decomposition is a popular dimensionality-reduction method for multiway data. Dimensionality reduction is often sought after since many high-dimensional tensors have low intrinsic rank relative to the dimension of the ambient measurement space.

Tensor-CUR Decompositions for Tensor-Based Data [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 2006
Motivated by numerous applications in which the data may be modeled by a variable subscripted by three or more indices, we develop a tensor-based extension of the matrix CUR decomposition. The tensor-CUR decomposition is most relevant as a data analysis tool when the data consist of one mode that is qualitatively different from the others. In this case,

DAO-CP: Data-Adaptive Online CP decomposition for tensor stream

open access: yesPLoS ONE, 2022
How can we accurately and efficiently decompose a tensor stream? Tensor decomposition is a crucial task in a wide range of applications and plays a significant role in latent feature extraction and estimation of unobserved entries of data. The problem of

Skew-symmetric tensor decomposition [PDF]

open access: yesCommunications in Contemporary Mathematics, 2019
We introduce the “skew apolarity lemma” and we use it to give algorithms for the skew-symmetric rank and the decompositions of tensors in [Formula: see text] with [Formula: see text] and [Formula: see text]. New algorithms to compute the rank and a minimal decomposition of a tritensor are also presented.
