Wasserstein Gradient Flows of MMD Functionals with Distance Kernel and Cauchy Problems on Quantile Functions

Richard Duong, Viktor Stein, Robert Beinert +2

We give a comprehensive description of Wasserstein gradient flows of maximum mean discrepancy (MMD) functionals $F_{I^} ½ := MMD_{K}^{2} (\cdot, I^½)$ towards given target mea…

Telegrapher's Generative Model via Kac Flows

Richard Duong, Jannis Chemseddine, Peter K. Friz +1

We break the mold in flow-based generative modeling by proposing a new model based on the damped wave equation, also known as telegrapher's equation. Similar to the diffusion equat…

Wasserstein Gradient Flows of MMD Functionals with Distance Kernels under Sobolev Regularization

Richard Duong, Nicolaj Rux, Viktor Stein +1

We consider Wasserstein gradient flows of maximum mean discrepancy (MMD) functionals $MMD_{K}^{2} (\cdot, I^½)$ for positive and negative distance kernels $K (x, y) := \pm ∣ x - y ∣$ an…
