WebLet us define the smoothed 2-Wasserstein distance: W 2, e ( p, q) = inf π ∈ Π ( p, q) ∑ i, j π i, j d 2 ( i, j) − λ E ( π) The benefit of the entropy term is that the resulting function is strongly concave [Peyre 2024] and that we can therefore more easily find a solution.

On the other hand, the Fisher metric is hyperbolic, with metric d s 2 = 1 σ 2 ( d μ 2 + 2 d σ 2). As a result, when the variance is large enough, the distance in the Fisher-Rao metric will be smaller than in the Wasserstein metric.
