Hellinger and Wasserstein are the two main geodesic distances on probability distributions. While both minimize the same energy, they differ in their interpolation methods: Hellinger focuses on density, whereas Wasserstein emphasizes position displacements.

Mirror and Preconditioned Gradient Descent in Wasserstein Space
As the problem of minimizing functionals on the Wasserstein space encompasses many applications in machine learning, different optimization algorithms on $\mathbb{R}^d$ have received their counterpart...

We propose a Generalized Sliced Wasserstein method that provides an approximated transport plan and which admits a differentiable approximation.

New paper accepted to ICML! We present a novel policy optimization algorithm for continuous control with a simple closed form which generalizes DDPG, SAC etc. to generic stochastic policies: Wasserstein Policy Optimization (WPO).

On Nakba Day let's recall British complicity in covering up the horrors of 1948 and the years preceding it. Below, a Guardian article from 1977 by the Historian Bernard Wasserstein reveals the destruction of key documents related to Palestine by the British State in the decade after the Nakba.

whereas with a Wasserstein penalty, the model assigns a finite penalty. though you have another problem entirely with Wasserstein penalties, which is that computing them exactly is ... very computationally painful, and if you do calculate them in high dimensions concentration of measure ruins them.
