Multi-subspace power method for decomposing partially symmetric tensors
Kexin Wang, João M. Pereira, Joe Kileel +1
We present an algorithm for low rank decomposition of tensors of any symmetry type, from fully asymmetric to fully symmetric. It recovers the decomposition one summand at a time vi…

Learning Paths from Signature Tensors
Max Pfeffer, Anna Seigal, Bernd Sturmfels
Matrix congruence extends naturally to the setting of tensors. We apply methods from tensor decomposition, algebraic geometry and numerical optimization to this group action. Given…
