arXiv:2605.29373v1 Announce Type: new Abstract: Solving high-dimensional PDE-governed inverse problems is often challenging due to complex non-Gaussian posterior distributions, expensive forward model evaluations, and misspecified prior information. To address these issues, we propose a deep adaptive dimension-reduction Bayesian inference framework based on the Variational Flow (VF) model. Since standard normalizing flows are restricted by bijective mappings and cannot directly reduce dimensions, VF overcomes this limitation by integrating VAE-based nonlinear dimension reduction with dual norm
This research addresses a fundamental challenge in high-dimensional Bayesian inference, which is becoming increasingly critical with complex AI models and scientific simulations.
Improved capabilities in Bayesian inference through dimension reduction can accelerate scientific discovery, optimize AI development, and enhance predictive modeling in various fields.
The ability to efficiently handle high-dimensional, non-Gaussian posterior distributions makes previously intractable inverse problems more solvable, potentially leading to more accurate and robust models.
