Finite Difference Nets:一个求解演化偏微分方程的深度递归框架

Finite Difference Nets: A Deep Recurrent Framework for Solving Evolution PDEs

Cheng Chang, Liu Liu, Tieyong Zeng

摘要:

采用深度学习方法来研究偏微分方程(PDE)已经成为一种新兴趋势。在本文中,我们引入了一个深度递归框架,用于在不生成大规模数据集的情况下求解时间依赖的偏微分方程。我们通过探索传统数值方法(例如有限差分格式)与深度神经网络(特别是卷积和全连接神经网络)之间可能的联系,提供了一个新的视角,即不同类型的架构。我们提出的方法将显示其有效性和效率,在求解具有积分形式的偏微分方程模型,特别是,我们测试单程波方程和守恒律组。

英文摘要:

There has been an arising trend of adopting deep learning methods to study partial differential equations (PDEs). In this paper, we introduce a deep recurrent framework for solving time-dependent PDEs without generating large scale data sets. We provide a new perspective, that is, a different type of architecture through exploring the possible connections between traditional numerical methods (such as finite difference schemes) and deep neural networks, particularly convolutional and fully-connected neural networks. Our proposed approach will show its effectiveness and efficiency in solving PDE models with an integral form, in particular, we test on one-way wave equations and system of conservation laws.
