New research explores Wasserstein gradient flows for Maximum Mean Discrepancy

Researchers have published a paper detailing Wasserstein gradient flows for Maximum Mean Discrepancy (MMD) using energy kernels. The study addresses challenges in applying standard gradient flow theory to nonsmooth kernels, particularly in higher dimensions. The paper proves global well-posedness for probability densities under specific conditions and explores the behavior of associated N-particle systems, including noncollision properties and convergence to continuum flow.
