New method uses iterative Gaussianization for improved density sampling

Researchers have introduced a novel iterative Gaussianization method designed for sampling from unnormalized densities. This technique repeatedly applies mean-field variational inference (MFVI) within rotated coordinate systems to approximate standard Gaussian distributions. The method's efficiency is enhanced by a principal component analysis (PCA)-based approach for selecting informative rotations, which significantly improves upon standard MFVI for Bayesian posterior sampling tasks.
