Decision-Aware Evaluation of Physics-Informed Surrogates

arXiv:2606. 07146v1 Announce Type: new Abstract: Physics-informed machine learning is often assessed by curve error, although engineering use depends on downstream decisions: ranking candidates, avoiding infeasible designs and limiting regret.

Frugal Bayesian Optimization: Scalable Surrogates for Data- and Resource-Limited Discovery

arXiv:2607. 29225v1 Announce Type: new Abstract: Bayesian Optimization (BO) is widely adopted for data-efficient optimization in scientific and engineering applications, yet its computational cost is rarely evaluated alongside optimization performance.

PhysicsBench: A Unified Leaderboard for Generative and Predictive Models in Engineering Design and Simulation

PhysicsBench is a unified benchmark and leaderboard that evaluates both generative and predictive AI models for engineering design and simulation under a single standardized procedure. It covers seven generation and prediction tasks across 1D, 2D, and 3D domains, ranking 66 models on nine industrial‑scale CAD/CFD/FEA datasets and public references, expanded into 28 configurations. The evaluation uses realistic, limited data scales and a common metric suite that captures geometric fidelity, physical‑field accuracy, and engineering‑specific validity, with rankings derived via a PageRank‑based dominance graph and a separate efficiency view.

Scientific Discovery under Validation Congestion via Multi-Fidelity Pairwise Rankings

The paper introduces PRISMS, a framework that uses expert pairwise rankings of varying fidelity to curate scientific designs without relying on data-intensive regression models. By escalating queries from lower- to higher-fidelity rankers based on Fisher-information, PRISMS improves discovery recall and reduces the number of screening rounds compared to regression-only and non‑escalated ranking methods. In optimization tasks, PRISMS outperforms Bayesian optimization by achieving higher hypervolume.
