Wasserstein Gradient Flows and Forward-Only Diffusion Are Not Enough for Multimodal Sampling
There has been a proliferation of sampling algorithms based on Wasserstein gradient flows (WGF) and forward-only diffusion processes (FODP), often accompanied by theoretical guarantees of exponentially fast convergence to the target distribution. These guarantees are frequently interpreted as evidence that such methods...
