Neural Sampling from Boltzmann Densities: Fisher-Rao Curves in the Wasserstein Geometry

Jannis Chemseddine, Christian Wald, Richard Duong +1

We deal with the task of sampling from an unnormalized Boltzmann density ${\rho }_D$ by learning a Boltzmann curve given by energies $f_t$ starting in a simple density ${\rho }_Z$. First, we e…
