Researchers have developed a new sampling method for Gibbs distributions using a finite number of particles. This technique, termed preconditioned regularized Wasserstein proximal sampling, approximates the score function with a regularized Wasserstein proximal operator. The method's diffusion component can be interpreted as a modified self-attention mechanism, similar to those in transformer architectures. Experiments show improved stability and performance in various applications, including Bayesian neural network training. AI
