Newton-Type Methods For Simultaneous Matrix Diagonalization
Rima Khouja, Bernard Mourrain, Jean-Claude Yakoubsohn
This paper proposes a Newton-type method to solve numerically the eigenproblem of several diagonalizable matrices, which pairwise commute. A classical result states that these matr…

Riemannian Newton optimization methods for the symmetric tensor approximation problem
Rima Khouja, Houssam Khalil, Bernard Mourrain
The Symmetric Tensor Approximation problem (STA) consists of approximating a symmetric tensor or a homogeneous polynomial by a linear combination of symmetric rank-1 tensors or pow…
