论文摘要
这项工作提出了一个自动编码器神经网络,作为解决偏微分方程(PDE)的投影方法的非线性概括。提出的深度学习体系结构能够通过将PDE的动态完全集成到没有中间重建的情况下,从而生成PDE的动力学,然后将潜在溶液解码回原始空间。所学到的潜在轨迹是代表的,并分析了它们的物理合理性。它显示了正确正规化的神经网络的可靠性,以从单个路径的样本数据以及预测看不见的分叉的能力中学习动力学系统相位空间的全局特征。
This work proposes an autoencoder neural network as a non-linear generalization of projection-based methods for solving Partial Differential Equations (PDEs). The proposed deep learning architecture presented is capable of generating the dynamics of PDEs by integrating them completely in a very reduced latent space without intermediate reconstructions, to then decode the latent solution back to the original space. The learned latent trajectories are represented and their physical plausibility is analyzed. It is shown the reliability of properly regularized neural networks to learn the global characteristics of a dynamical system's phase space from the sample data of a single path, as well as its ability to predict unseen bifurcations.
