预测复杂物理过程中的时空动态通常依赖计算成本高的数值方法,或训练成本高、误差累积且泛化能力差的数据驱动神经网络。本文提出多分辨率有限体积启发式网络MuRFiV,结合有限体积法的全局守恒性与深度学习的局部表达能力。通过将偏微分方程(PDE)信息嵌入网络结构,该模型在伯格斯方程、浅水方程和不可压缩纳维-斯托克斯方程等系统上表现出色,实现了强长期预测精度,并在极长自回归推演中保持稳定,显著优于纯数据驱动的神经网络基线。结果表明,将多分辨率学习与有限体积启发归纳偏置结合,可有效提升复杂动态系统的准确性和鲁棒性预测能力。

原文摘要 · Abstract (English)

Predicting complex spatiotemporal dynamics in physical processes often demands computationally expensive numerical methods or data-driven neural networks that suffer from high training costs, error accumulation, and limited generalizability to unseen parameters. An effective approach to address these challenges is leveraging physics priors in training neural networks, known as physics-informed deep learning (PiDL). In this work, we introduce the Multi-Resolution Finite-Volume-inspired network, MuRFiV, designed to capitalize on the conservative property of finite volume on the global scale and the expressive power of deep learning on the local scale. We demonstrate the effectiveness of MuRFiV on several spatio-temporal systems governed by partial differential equations (PDEs), including Burgers' equation, shallow water equations, and incompressible Navier-Stokes equations. By embedding PDE information into the deep learning architecture, MuRFiV achieves strong long-term prediction accuracy and remains stable over very long autoregressive rollouts, significantly outperforming data-driven neural network baselines. This result highlights the promise of combining multiresolution learning with finite-volume-inspired inductive bias for accurate and robust long-term prediction of complex dynamics.
