用PaddlePaddle复现Fourier Neural Operator 简介 Fourier Neural Operator 模型是Fourier Neural Operator for Parametric Partial Differential Equations一文中提出的模型。该模型尝试去学习基于傅里叶变换的有限维算子的参数化,去数值逼近一些偏微分方程。该模型比起其他尝试用深度学习求解复杂的偏微分方程数值解的模型相比,具...
In this work, we formulate a new neural operator by parameterizing the integral kernel directly in Fourier space, allowing for an expressive and efficient architecture. We perform experiments on Burgers' equation, Darcy flow, and Navier-Stokes equation. The Fourier neural operator is the first ML...

FNO在机器学习求解偏微分方程领域比较火热,是继PINN后一种所谓 "算子学习''的范式,但因为论文中涉及大量数学推导和灵感的阐述让人很难快速理解。通过阅读源码,我们会发现它的实现其实并不复杂。本…

The Fourier Neural Operator (FNO) [1] is a neural operator with an integral kernel parameterized in Fourier space. This allows for an expressive and efficient architecture. Applications of the FNO include weather forecasting and, more generically, finding efficient solutions to the Navier-Stokes ...

用PaddlePaddle复现Fourier Neural Operator 训练流程(当前仍有bug) 下面的代码定义了一个简单的训练流程。使用官方代码给出的Darcy flow 数据集,我们尝试训练一个FNO模型。训练过程中,我们使用了Adam优化器优化全体模型参数,我们会发现模型基本会收敛在一个loss还比较高的时候,复原的效果也不如预期。 In [1] import ...
