Riemannian optimization on tensor products of Grassmann manifolds: Applications to generalized Rayleigh-quotients
O. Curtef, G. Dirr, U. Helmke
We introduce a generalized Rayleigh-quotient on the tensor product of Grassmannians enabling a unified approach to well-known optimization tasks from different areas of numerical l…
