Researchers have developed a new method for Stein Variational Gradient Descent (SVGD) that addresses the issue of infinite self-interaction when using singular Riesz kernels. This modified approach, termed periodic Riesz SVGD, removes self-interaction and provides a theoretical framework for long-time particle sampling. The study proves that under specific conditions, the empirical-measure law converges to the target distribution, extending previous methods for smooth kernels to singular interactions. AI
