Wasserstein gradient flows of Maximum Mean Discrepancy with energy kernels

Matthew Rosenzweig, Dejan Slepčev, Lihan Wang

We study the Wasserstein gradient flow of the squared Maximum Mean Discrepancy (MMD) generated by the nonsmooth energy kernels $K (z) = - ∣ z ∣^{q}$ , $0 < q < 2$ . In dimensions $d \geq 2$ , the co…

On the entropic convergence for piecewise deterministic samplers: speedup and obstruction

Pierre Monmarché, Lihan Wang

For piecewise deterministic samplers such as Randomized Hamiltonian Monte Carlo (RHMC), Bouncy Particle Sampler (BPS) or Zig-Zag Process (ZZP), long-time exponential convergence ra…
