Thanks for your contribution!

复现Domino有两个问题：

目前只复现了模型内容，另外还有前处理和后处理部分，需要的CPU配置和内存非常高，aistudio上无法跑通
官方没有提供预训练权重

luotao1 · 2025-03-05T12:02:40Z

请先提交 RFC 设计文档

wangguan1995 · 2025-03-10T11:27:52Z

不好意思这里任务描述有误，需要改为【推理】和【训练】

luotao1 · 2025-03-11T02:32:20Z

@wangguan1995 可以提PR修改下任务描述 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#no13-domino-%E8%AE%BA%E6%96%87%E5%A4%8D%E7%8E%B0

xiaoyewww · 2025-03-15T15:49:56Z

@wangguan1995 目前模型已经能正常训练，精度通过Padiff验证通过。训练代码存在随机性，每个step前处理数据没法通过随机数种子固定。
目前还有需要验证的任务有：
（1）目前缺少数据集，仅通过一个样本进行训练，50个epoch loss正常下降
（2）推理代码已经适配，但前处理部分仍需进行点云处理，aistudio上无法处理，这部分需要继续验证

wangguan1995 · 2025-04-03T08:20:49Z

目前代码仓库存在大量相对路径
下载脚本目前有一些问题（aws自己的问题，先标记在文档里）
run_1作为验证训练的数据，10个epoch的torch对比日志贴在这里
需要做的是前向loss 1e-5级别的对齐

+外部空气动力学涉及高雷诺数Navier-Stokes方程求解，传统CFD方法计算成本高昂。神经算子通过端到端映射提升了效率，但面临多尺度耦合建模与长期预测稳定性不足的挑战。Decomposable Multi-scale Iterative Neural Operator（Domino）提出可分解多尺度架构，通过分层特征解耦、迭代残差校正及参数独立编码，显著提升跨尺度流动建模精度与泛化能力。实验显示，其计算速度较CFD快2-3个量级，分离流预测精度较FNO等模型提升约40%，为飞行器设计等工程问题提供高效解决方案。

		外部空气动力学涉及高雷诺数Navier-Stokes方程求解，传统CFD方法计算成本高昂。神经算子通过端到端映射提升了效率，但面临多尺度耦合建模与长期预测稳定性不足的挑战。Decomposable Multi-scale Iterative Neural Operator（Domino）提出可分解多尺度架构，通过分层特征解耦、迭代残差校正及参数独立编码，显著提升跨尺度流动建模精度与泛化能力。实验显示，其计算速度较CFD快2-3个量级，分离流预测精度较FNO等模型提升约40%，为飞行器设计等工程问题提供高效解决方案。
