Sliced Wasserstein distance between probability measures on Hilbert spaces

Abstract

The sliced Wasserstein distance as well as its variants have been widely considered in comparing probability measures defined on ${\mathbb{R}}^d$. Here we derive the notion of sliced Wasserstein distance for measures on an infinite dimensional separable Hilbert spaces, depict the relation between sliced Wasserstein distance and narrow convergence of measures and quantize the approximation via empirical measures.
