作者: Mikael Sørensen Lieven De Lathauwer KU Leuven Kulak Engineering and Technology Kortrijk Belgium
Tensors have proven to be useful tools for array processing. Most attention has been paid to separable arrays, which lead to a Canonical Polyadic Decomposition (CPD). For more general geometries, and in particular for... 详细信息
