Kronecker product of tensors
WebThis regression problem arises in each step of the widely-used alternating least squares (ALS) algorithm for computing the Tucker decomposition of a tensor. We present the first subquadratic-time algorithm for solving Kronecker regression to a (1+ ε) ( 1 + ε) -approximation that avoids the exponential term O(ε−N) O ( ε − N) in the ...

Did you know?
WebKronecker product operators on third and fourth order tensors are introduced. The tensorial nature of Kronecker products of tensors is established. Finally, conditions for symmetry classes in fourth order tensors are stated in terms of Kronecker products. http://tensorly.org/stable/modules/generated/tensorly.tenalg.kronecker.html
