  • 用潜变量振子群动态表示解,捕捉局部相互作用
  • 在多种偏微分方程基准上优于现有方法,误差更低
  • 振子同步程度可解释预测误差,具可解释性

算子学习是计算科学中的前沿方向,特别适用于需在不同物理配置下反复求解偏微分方程(PDE)的问题。现有架构多在固定基底下表示解算子,虽适于全局结构,但难以刻画空间局部相互作用现象。本文受连续极限下耦合振子系统可描述一类广义PDE的启发,提出柯朗托神经算子(Kuramoto Neural Operator, KNO),通过潜变量振子群的演化来表示解。在多个PDE基准测试中,KNO展现出优异的预测性能,相较现有方法有明显提升。实验还包含详尽消融研究,量化了各模块贡献。进一步发现,模型预测误差与潜变量振子的集体动力学密切相关,随其同步程度系统性变化,揭示了内在工作机制。

原文摘要 · Abstract (English)

Operator learning is a rapidly advancing area of computational science. It is particularly well suited to problems where a partial differential equation (PDE) must be solved repeatedly under varying physical configurations. Most existing architectures represent the solution operator in a fixed basis. While this assumption is well aligned with global structures, it is less suitable for phenomena governed by local interactions in physical space. We explore an alternative perspective motivated by the observation that the continuum limit of coupled oscillator systems can describe a broad class of PDEs. Building on this idea, we introduce the Kuramoto Neural Operator (KNO), which represents the solution through the evolution of a latent field of interacting oscillators. Across a diverse collection of PDE benchmarks, KNO achieves strong predictive performance, with improvements over competing approaches. Our experimental evaluation also includes an extensive ablation study that quantifies the contribution of each architectural component incorporated into KNO. Furthermore, we show that the model's prediction error is closely linked to the collective dynamics of the latent oscillators. It varies systematically with their degree of synchronization, providing insights into the underlying mechanisms.
