- On the best low multilinear rank approximation of higher-order tensors
Mariya Ishteva (Université catholique de Louvain, Department of Mathematical Engineering) Co-authors: PA. Absil, S. Van Huffel, L. De Lathauwer Abstract: Higher-order tensors can be thought of higher-dimensional tables of numbers. Many fields, such as higher-order statistics and biomedical signal processing exploit such multi-way arrays. We focus on the best low multilinear rank approximation, used for signal subspace estimation and dimensionality reduction. Standard optimization algorithms face a difficulty caused by an invariance property of the cost function. We suggest three geometric algorithms, based on Newton's method, trust-region scheme and conjugate gradients. We also discuss the issue of local minima.
