Abstract(in English) | It is useful to exploit an empirical mean from a dataset to smooth-out data and to alleviate measurement errors and random fluctuations. In this paper, three different averaging algorithms on the compact Stiefel manifold are constructed. These methods are operations exploiting the relationship between either a manifold and its tangent space or a Lie group and its Lie algebra. Comparison of convergence between constructed methods and examination of computational burden due to the difference of calculations are performed by numerical experiments. |
