Diffusion models enhance Bayesian FWI for subsurface reconstruction

By PulseAugur Editorial · [1 sources] ·

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

IMPACT This research could lead to more accurate subsurface imaging and better uncertainty quantification in geological surveys.

    Structure-aware Bayesian full waveform inversion via diffusion-regularized Stein variational gradient descent

    arXiv:2610.19187v1 Announce Type: cross Abstract: Full waveform inversion (FWI) is a powerful tool for high-resolution subsurface model reconstruction, but it remains highly nonlinear and ill-posed, especially when the initial model is inaccurate or the acquired data are noisy an…
