Approximated logarithmic maps on Riemannian manifolds and their applications

Recently, optimization problems on Riemannian manifolds involving geodesic distances have been attracting considerable research interest. To compute geodesic distances and their Riemannian gradients, we can use logarithmic maps. However, the computational cost of logarithmic maps on Riemannian manif...
