| ### 1.3 意义 | ||
|
|
||
| > 复现 DPMM 代码，能够使用 DPMM 模型进行训练、验证、导出。 |
| ### 1.2 功能目标 | ||
|
|
||
| * 复现 DPMM 代码，实现完整的流程，包括：训练、验证、导出。 | ||
| * 保持精度与论文精度一致，相对误差在 ±10% 以内。 |

数据要盘点清楚：
- 40个，不同的初始边界条件的，视频数据，进行训练
- 测试集4组、训练集36组，按照 9:1划分
- 每组数据320个帧，一共10秒钟时长
- 实际上原数据是1024x1024，进行了下采样，分辨率为256x256
- 每次送进网络的，有3个时间帧的图片（代码）
| 1. 数据预处理 | ||
| 2. 模型构建 | ||
| 3. 超参数设定 | ||
| 4. 验证训练模型的 rel. error |

注意：
- 误差只有方程部分是相对误差
- 物理场是L2逐点绝对误差，取平均
| ## 6. 可行性分析和排期规划 | ||
