Multi-Dataset Inverse Problem Solving with Distributed Generative AI

Read the original on arXiv Machine Learning →

The paper introduces a generalized framework for solving inverse problems across multiple heterogeneous datasets using distributed generative AI. It extends the SAGIPS framework to handle non‑identically distributed data, employing separate forward operators and discriminators for each dataset while guiding a shared generator toward global parameter consistency. Validation on a multi‑detector scattering experiment demonstrates robustness to varying data fidelities and scalability on multi‑GPU systems.

Inverse Problems Conditioned on Observation Ensembles: Applications and Methods

The paper introduces the Ensemble-conditioned Inverse Problem (EIP), a multivariate statistical framework for inferring an ensemble that follows the pushforward of a prior through a forward process. It applies to fields such as high‑energy physics, full waveform inversion, and inverse imaging, and proposes non‑iterative inference‑time methods using ensemble inverse generative models that avoid explicit forward model use during inference. The authors demonstrate the approach on synthetic and real datasets and provide code for replication.

PosteriorBench: From Point Estimates to Posterior Matching in Evaluating Generative Inverse Solvers

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.
