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, …
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.
