Direct Intermediate Initialization for Tilted Diffusion Samplers

「直接中間初始化」技術：突破傾斜擴散採樣器的有限粒子瓶頸

This paper introduces Direct Intermediate Initialization, which pulls back tilted diffusion targets to a softened clean-space posterior and maps samples via a Gaussian bridge, boosting SMC sampler performance under finite-particle constraints.
