摘要:

本文介绍了一种从数据中寻找一类非线性积分微分算子的回归方法。该方法用神经网络和傅立叶变换对空间算子进行参数化,使得它可以适合一类非线性算子,而不需要先验选择的算子库。我们验证了该方法可以恢复的分数阶热方程和Kuramoto-Sivashinsky方程的数值解的空间运营商。

英文摘要:

This note introduces a regression technique for finding a class of nonlinear integro-differential operators from data. The method parametrizes the spatial operator with neural networks and Fourier transforms such that it can fit a class of nonlinear operators without needing a library of a priori selected operators. We verify that this method can recover the spatial operators in the fractional heat equation and the Kuramoto-Sivashinsky equation from numerical solutions of the equations.
