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,具备以下几个很重要的特点: 训练比较容易,可以用...
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...
Fourier Neural OperatorThe 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 ...
