Approximating with Kronecker Products

Abstract:  I will give an overview of the following approximation problem.

Given a matrix A and a factorization of its dimensions, find matrices B and C of the corresponding dimensions whose Kronecker product is as close as possible to A in Frobenius norm:

                          min || A - Bx C ||_F
                          B,C

Various constrained Kronecker product approximation problems are also considered along with examples of where such approximations are useful. See the Kronecker products home page  for more details.
