An algebraic algorithm for rank-2 ParaTuck-2 decomposition
Résumé
In this note we consider the problem of ParaTuck-2 decomposition of a complex three-way tensor.
We provide an algebraic algorithm for finding the rank-2 decomposition for ParaTuck-2 tensors.
Our approach relies only on linear algebra operations and is based on finding the kernel of a structured matrix constructed from the tensor.
