Wasserstein Propagation for Reverse Diffusion under Weak Log-Concavity: Exploiting Metric Mismatch via One-Switch Routing
arXiv:2603.19670v2 Announce Type: replace
Abstract: Existing analyses of reverse diffusion typically propagate sampling error in the Euclidean geometry underlying \(\Wtwo\) throughout the reverse trajectory. Under weak log-concavity, this can be subop…
