Stochastic Completeness for Landmark Shape Spaces with Induced Metrics
Karen Habermann, Mao Nishino, Stefan Sommer
Landmark shape spaces arise from configurations of distinct landmarks with rigid motions factored out and scale normalized. When equipped with sufficiently regular metrics inhe…
Stochastic completeness for landmark space
Karen Habermann, Stefan Sommer
We study stochastic completeness for landmark spaces equipped with Riemannian metrics induced by right-invariant metrics on subgroups of the diffeomorphism group of the shape domai…
Characterization of geodesic completeness for landmark space
Karen Habermann, Stephen C. Preston, Stefan Sommer
We provide a full characterization of geodesic completeness for spaces of configurations of landmarks with smooth Riemannian metrics that satisfy a rotational and translation invar…
Score matching for sub-Riemannian bridge sampling
Erlend Grong, Karen Habermann, Stefan Sommer
Simulation of conditioned diffusion processes is an essential tool in inference for stochastic processes, data imputation, generative modelling, and geometric statistics. Whilst si…
