Contributions: In this line of research, we set theoretical foundations and develop algorithms for reliable L1-norm based tensor analysis. Our contributions are as follows. We present generalized L1-Tucker decomposition for N-way tensors.

WebApr 11, 2024 · Higher-order dynamic mode decomposition (HODMD) has proved to be an efficient tool for the analysis and prediction of complex dynamical systems described by data-driven models. In the present paper, we propose a realization of HODMD that is based on the low-rank tensor decomposition of potentially high-dimensional datasets. It is … Web35-34 (L) Rock Ridge vs. Lightridge.

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, … Websparse tensor (outliers). Another straightforward robust reformulation is L1-Tucker [21, 22], which derives by simple substitution of the L2-norm in the Tucker formulation by the more robust L1-norm (not to be confused with sparsity-inducing L1-norm regularization schemes).
