Researchers have developed a novel approach to full waveform inversion (FWI) by integrating a learned diffusion model with Annealed Stein Variational Gradient Descent (ASVGD). This method enhances subsurface model reconstruction by using a diffusion model as a learned geological projection operator, guiding particles toward plausible velocity models. The diffusion-regularized ASVGD-FWI framework improves inversion stability and the interpretability of uncertainty estimates, particularly in complex geological regions. AI
