Learning spatiotemporal piecewise-geodesic trajectories from longitudinal manifold-valued data

NeurIPS 2017poster

We introduce a hierarchical model which allows to estimate a group-average piecewise-geodesic trajectory in the Riemannian space of measurements and individual variability. This model falls into the well defined mixed-effect models. The subject-specific trajectories are defined through spatial and t…

Learning spatiotemporal trajectories from manifold-valued longitudinal data

NeurIPS 2015poster

We propose a Bayesian mixed-effects model to learn typical scenarios of changes from longitudinal manifold-valued data, namely repeated measurements of the same objects or individuals at several points in time. The model allows to estimate a group-average trajectory in the space of measurements. Ran…
