arXiv:2605.27756v1 Announce Type: cross Abstract: High-performance computing enables simulation of high-dimensional physical systems, but downstream analyses such as inverse problems and control remain computationally expensive, motivating model order reduction (MOR) to construct efficient low-dimensional surrogates. Proper Orthogonal Decomposition (POD), a widely adopted data-driven MOR method, projects dynamics onto linear subspaces spanned by the most energetic modes. However, POD struggles for problems with slowly decaying Kolmogorov \(n\)-widths, such as advection-dominated and turbulent
The increasing complexity of physical system simulations driven by high-performance computing necessitates more efficient model reduction techniques to handle computational expense.
This research advances the core methodologies for simulating complex physical systems, which has broad implications for engineering, scientific discovery, and AI applications in physical domains.
New methods for low-dimensional surrogates of high-dimensional physics simulations promise more efficient analysis and control, particularly for problems where traditional methods like POD struggle.
