## 1. 概述 | ||
|
||
### 1.1 相关背景 | ||
|
||
[NO.15 Diffeomorphism Neural Operator 论文复现](https://github.com/PaddlePaddle/community/blob/master/hackathon/hackathon_8th/%E3%80%90Hackathon_8th%E3%80%91%E4%B8%AA%E4%BA%BA%E6%8C%91%E6%88%98%E8%B5%9B%E2%80%94%E5%A5%97%E4%BB%B6%E5%BC%80%E5%8F%91%E4%BB%BB%E5%8A%A1%E5%90%88%E9%9B%86.md#no15-diffeomorphism-neural-operator-%E8%AE%BA%E6%96%87%E5%A4%8D%E7%8E%B0) | ||
|
||
论文主要尝试解决在不同几何域和参数下求解偏微分方程(PDEs)的问题。传统的数值方法在处理不同几何域和参数时非常耗时和资源密集,因为每次参数或几何域发生变化都需要重新计算。论文提出了一种新的神经算子学习框架,称为Diffeomorphism Neural Operator(DNO),该框架可以将不同物理域映射到一个通用域上,从而在通用域上学习PDE的解,进而提高模型的泛化能力和计算效率。 | ||
|
||
### 1.2 功能目标 | ||
|
||
1. 复现 Diffeomorphism-Neural-Operator 代码,实现完整的推理流程。 | ||
2. 保持精度与论文精度一致,相对误差在 ±10% 以内。 | ||
3. 产出论文相关文档、图片、视频等。 | ||
|
||
### 1.3 意义 | ||
|
||
复现 Diffeomorphism-Neural-Operator 代码,能够使用 Diffeomorphism-Neural-Operator 模型进行推理。 | ||

## 2. PaddleScience 现状 | ||
|
||
PaddleScience 套件暂无 Diffeomorphism-Neural-Operator 代码案例。 | ||
|
||
## 3. 目标调研 | ||
|
||
- 论文解决的问题: | ||
Diffeomorphism-Neural-Operator 模型用于在不同几何域和参数下高效求解偏微分方程(PDEs),DNO通过将不同物理域微分同胚映射到一个通用域上,将不同域上的PDE求解问题转化为通用域上的问题。该框架结合了物理域和通用域的几何信息,通过神经算子学习参数函数与解函数之间的映射关系。 | ||
