WebIn mathematics, Tucker decomposition decomposes a tensor into a set of matrices and one small core tensor. It is named after Ledyard R. Tucker although it goes back to Hitchcock in 1927. Initially described as a three-mode extension of factor analysis and principal component analysis it may actually be generalized to higher mode analysis, … WebDec 29, 2024 · The proposed approach uses three and four dimensional tensors to predict complete city traffic flow at once using modified Tucker tensor decomposition. Our modified Tucker decomposition technique uses CUR factorization, that gives the advantage of restoring the original values of matrix during approximation for prediction. … WebL1-norm just sums the absolute value of error, which re-duces the inﬂuence of the outliers comparing to the Frobe-nius norm. So the more robust against outlier version of Tucker tensor decomposition is formulatedusing L1-norm.

Websistance has been recently attained by algorithms for L1-norm reformulation of Tucker2 decomposition of 3-way tensors (L1-Tucker2) [15], [16]. In [17], two new methods for robust L1-norm Tucker decomposition of general-order tensors were proposed, namely L1-HOSVD and L1-HOOI. In this paper, we propose a novel method that generates a WebJan 1, 2024 · Tensor train decomposition. TT decomposition is proposed in [43] and is also known as matrix product state (MPS) in the area of quantum physics. Since it can avoid the recursive computation of binary trees and is mathematically easy to solve due to its compact form, it has attracted a lot of attention in recent years.
