New Wasserstein Mahalanobis distance recovers latent geometry

Researchers have introduced a new metric called the Wasserstein Mahalanobis distance, which extends the concept of Mahalanobis distance from multivariate data to probability measures. This new distance metric utilizes optimal transport displacement fields and covariance operators on Wasserstein tangent spaces. The work demonstrates that this construction can recover latent geometry, analogous to nonlinear independent component analysis, and approximates the classical Mahalanobis distance for Gaussian measures under smooth transformations.
