arXiv:2606.07926v1 Announce Type: cross Abstract: Optimal transport couplings are probabilistic objects, while many learning pipelines require deterministic maps. In Euclidean space, barycentric projection converts a coupling into a map by taking conditional expectations, but on a Riemannian manifold curvature and cut loci make this operation nontrivial. We develop a framework for barycentric projections of transport couplings on Riemannian manifolds. The intrinsic projection maps each source point to the conditional Fr\'echet mean of its destination law and is shown to be the best determinist
This research addresses a fundamental mathematical challenge in optimal transport theory, which is critical for advancing machine learning applications that require robust data mapping and comparison in complex geometric spaces.
Improved mathematical frameworks for optimal transport on Riemannian manifolds can lead to more accurate and robust AI models, especially in fields like computer vision, natural language processing, and robotics where data often resides in non-Euclidean spaces.
The development of a rigorous framework for barycentric projections on Riemannian manifolds provides a new tool for converting probabilistic couplings into deterministic maps, overcoming current limitations in high-dimensional data analysis.
