The paper presents a method that combines flow‑matching models with energy‑based modeling to explicitly construct scalar energy functions for physical fields. These energies are derived from a matching regression objective on a linear Gaussian interpolation, avoiding variational approximations or extra MCMC steps, and can be used for energy‑corrected data generation, out‑of‑distribution detection, and posterior sampling in inverse problems. The approach enables general MCMC samplers that reduce PDE residuals and spectral distance, and it demonstrates that combining data‑driven and physics‑based energies improves OOD detection accuracy.

PosteriorBench is a new benchmark that evaluates how well generative inverse solvers recover full posterior distributions rather than just a single reconstruction. It tests four physics-based inverse problems—Darcy flow inversion, Poisson source recovery, carbon capture and storage, and light transport material inference—using high-fidelity reference posteriors generated by rejection sampling and MCMC. The benchmark employs five metrics (posterior-mean error, posterior-standard-deviation error, maximum mean discrepancy, sliced Wasserstein distance, and radially averaged power-spectrum error) to assess pointwise accuracy, uncertainty, distributional alignment, and global frequency fidelity, revealing significant distribution-matching gaps in current solvers and highlighting the importance of neural operators, guidance weights, and generation noise for posterior-variance calibration.

The paper introduces a two‑stage physics‑informed deep learning framework for solving inverse problems in partial differential equations with jump discontinuities in coefficients. The first stage uses a dual‑network architecture to approximate the PDE solution and a relaxed continuous surrogate of the coefficient field, followed by Bayesian inference with Gaussian mixture and birth‑death Markov chain models to estimate coefficient regimes and transition regions. The second stage reformulates the inverse problem as a constrained estimator with a hard piecewise‑constant coefficient representation, achieving accurate parameter estimation with acceptable computational costs across various PDE types.
