Latent Diffusion Posterior Sampling with Surrogate Likelihood Guidance for PDE Inverse Problems
Yuanzhe Wang, Alexandre M. Tartakovsky
cs.CE · cs.LG
We propose latent-space diffusion posterior sampling (L-DPS), an approximate Bayesian framework for high-dimensional inverse problems governed by partial differential equations (PDEs). The method addresses three challenges in PDE-constrained inversion: implicit sample-based priors without tractable densities, high-dimensional spatially distributed parameters, and the high cost of repeated forward-model evaluations during posterior sampling....
