WebIn this work we study L1-Tucker, an L1-norm reformulation of the general Tucker decomposition of N-way tensors. Then, we propose two new algorithms for the solution of L1-Tucker, namely L1-HOSVD and L1-HOOI, accompanied by formal convergence and complexity analysis.

WebJul 26, 2024 · Non-negative Tucker decomposition (NTD) has been developed as a crucial method for non-negative tensor data representation. However, NTD is essentially an unsupervised method and cannot take advantage of label information. In this paper, we claim that the low-dimensional representation extracted by NTD can be treated as the …
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, … financial management act malawiWebThis outlier sensitivity of Tucker is often attributed to its L2/Frobenius norm based formulation.
