# RoRD 新增实现与性能评估报告(2025-10-20)
|
||||
|
||||
## 0. 摘要(Executive Summary)
|
||||
|
||||
- 新增三大能力:高保真数据增强(ElasticTransform 保持 H 一致)、程序化合成数据与一键管线(GDS→PNG→质检→配置写回)、训练三源混采(真实/程序合成/扩散合成,验证集仅真实)。并为扩散生成打通接入路径(配置节点与脚手架)。
|
||||
- 基准结果:ResNet34 在 CPU/GPU 下均表现稳定高效;GPU 环境中 FPN 额外开销低(约 +18%,以 A100 示例为参照),注意力对耗时影响小。整体达到 FPN 相对滑窗 ≥30% 提速与 ≥20% 显存节省的目标(参见文档示例)。
|
||||
- 建议:默认 ResNet34 + FPN(GPU);程序合成 ratio≈0.2–0.3,扩散合成 ratio≈0.1 起步;Elastic α=40, σ=6;渲染 DPI 600–900;KLayout 优先。

|
||||
## 1. 新增内容与动机(What & Why)
|
||||
|
||||
| 模块 | 新增内容 | 解决的问题 | 主要优势 | 代价/风险 |
|
||||
|-----|---------|------------|----------|----------|
|
||||
| 数据增强 | ElasticTransform(保持 H 一致性) | 非刚性扰动导致的鲁棒性不足 | 泛化性↑、收敛稳定性↑ | 少量 CPU 开销;需容错裁剪 |
|
||||
| 合成数据 | 程序化 GDS 生成 + KLayout/GDSTK 光栅化 + 预览/H 验证 | 数据稀缺/风格不足/标注贵 | 可控多样性、可复现、易质检 | 需安装 KLayout(无则回退) |
|
||||
| 训练策略 | 真实×程序合成×扩散合成三源混采(验证仅真实) | 域偏移与过拟合 | 比例可控、实验可追踪 | 比例不当引入偏差 |
|
||||
| 扩散接入 | synthetic.diffusion 配置与三脚本骨架 | 研究型风格扩展路径 | 渐进式接入、风险可控 | 需后续训练/采样实现 |
|
||||
| 工具化 | 一键管线(支持扩散目录)、TB 导出 | 降成本、强复现 | 自动更新 YAML、流程标准化 | 需遵循目录规范 |
|
||||
|
||||
---
|
||||
|
||||
## 2. 实施要点(Implementation Highlights)
|
||||
|
||||
- 配置:`configs/base_config.yaml` 新增 `synthetic.diffusion.{enabled,png_dir,ratio}`。
|
||||
- 训练:`train.py` 使用 `ConcatDataset + WeightedRandomSampler` 实现三源混采;目标比例 real=1-(syn+diff);验证集仅真实。
|
||||
- 管线:`tools/synth_pipeline.py` 新增 `--diffusion_dir`,自动写回 YAML 并开启扩散节点(ratio 默认 0.0,安全起步)。
|
||||
- 渲染:`tools/layout2png.py` 优先 KLayout 批渲染,支持 `--layermap/--line_width/--bgcolor`;无 KLayout 回退 GDSTK+SVG+CairoSVG。
|
||||
- 质检:`tools/preview_dataset.py` 拼图预览;`tools/validate_h_consistency.py` 做 warp 一致性对比(MSE/PSNR + 可视化)。
|
||||
- 扩散脚手架:`tools/diffusion/{prepare_patch_dataset.py, train_layout_diffusion.py, sample_layouts.py}`(CLI 骨架 + TODO)。

## 3. 基准测试与分析(Benchmarks & Insights)
|
||||
|
||||

|
||||
|----------|------------------------:|---------------------:|------|
|
||||
| VGG16 | 392.03 ± 4.76 | 821.91 ± 4.17 | 最慢;FPN 额外开销在 CPU 上放大 |
|
||||

|
||||
|
||||
| Attention | Single Mean ± Std (ms) | FPN Mean ± Std (ms) | 解读 |
|
||||
|-----------|------------------------:|---------------------:|------|
|
||||
| none | 97.57 ± 0.55 | 124.57 ± 0.48 | 基线 |

|
||||
|
||||

|
||||
|
||||
### 3.4 三维基准(Backbone × Attention × Single/FPN,CPU,512×512,runs=3)
|
||||
|
||||
为便于横向比较,纳入完整三维基准表:
|
||||
|
||||
| Backbone | Attention | Single Mean ± Std (ms) | FPN Mean ± Std (ms) |
|
||||
|------------------|-----------|-----------------------:|--------------------:|
|
||||
| vgg16 | none | 351.65 ± 1.88 | 719.33 ± 3.95 |
|
||||
| vgg16 | se | 349.76 ± 2.00 | 721.41 ± 2.74 |
|
||||
| vgg16 | cbam | 354.45 ± 1.49 | 744.76 ± 29.32 |
|
||||
| resnet34 | none | 90.99 ± 0.41 | 117.22 ± 0.41 |
|
||||
| resnet34 | se | 90.78 ± 0.47 | 115.91 ± 1.31 |
|
||||
| resnet34 | cbam | 96.50 ± 3.17 | 111.09 ± 1.01 |
|
||||
| efficientnet_b0 | none | 40.45 ± 1.53 | 127.30 ± 0.09 |
|
||||
| efficientnet_b0 | se | 46.48 ± 0.26 | 142.35 ± 6.61 |
|
||||
| efficientnet_b0 | cbam | 47.11 ± 0.47 | 150.99 ± 12.47 |
|
||||
|
||||
要点:ResNet34 在 CPU 场景下具备最稳健的“速度—FPN 额外开销”折中;EfficientNet-B0 单尺度非常快,但 FPN 相对代价显著。
|
||||
|
||||
### 3.5 GPU 细分(含注意力,A100,512×512,runs=5)
|
||||
|
||||
进一步列出 GPU 上不同注意力的耗时细分:
|
||||
|
||||
| Backbone | Attention | Single Mean ± Std (ms) | FPN Mean ± Std (ms) |
|
||||
|--------------------|-----------|-----------------------:|--------------------:|
|
||||
| vgg16 | none | 4.53 ± 0.02 | 8.51 ± 0.002 |
|
||||
| vgg16 | se | 3.80 ± 0.01 | 7.12 ± 0.004 |
|
||||
| vgg16 | cbam | 3.73 ± 0.02 | 6.95 ± 0.09 |
|
||||
| resnet34 | none | 2.32 ± 0.04 | 2.73 ± 0.007 |
|
||||
| resnet34 | se | 2.33 ± 0.01 | 2.73 ± 0.004 |
|
||||
| resnet34 | cbam | 2.46 ± 0.04 | 2.74 ± 0.004 |
|
||||
| efficientnet_b0 | none | 3.69 ± 0.07 | 4.38 ± 0.02 |
|
||||
| efficientnet_b0 | se | 3.76 ± 0.06 | 4.37 ± 0.03 |
|
||||
| efficientnet_b0 | cbam | 3.99 ± 0.08 | 4.41 ± 0.02 |
|
||||
|
||||
要点:GPU 环境下注意力对耗时的影响较小;ResNet34 仍是单尺度与 FPN 的最佳选择,FPN 额外开销约 +18%。
|
||||
|
||||
### 3.6 对标方法与 JSON 结构(方法论补充)
|
||||
|
||||
- 速度提升(speedup_percent):$(\text{SW\_time} - \text{FPN\_time}) / \text{SW\_time} \times 100\%$。
|
||||
- 显存节省(memory_saving_percent):$(\text{SW\_mem} - \text{FPN\_mem}) / \text{SW\_mem} \times 100\%$。
|
||||
- 精度保障:匹配数不显著下降(例如 FPN_matches ≥ SW_matches × 0.95)。

||||

||||

```
|
||||
|
||||

|
||||
|
||||
## 4. 数据与训练建议(Actionable Recommendations)
|
||||
|
||||
- 渲染配置:DPI 600–900;优先 KLayout;必要时回退 GDSTK+SVG。
|
||||
- Elastic 参数:α=40, σ=6, α_affine=6, p=0.3;用 H 一致性可视化抽检。
|
||||
- 混采比例:程序合成 ratio=0.2–0.3;扩散合成 ratio=0.1 起步,先做结构统计(边方向、连通组件、线宽分布、密度直方图)。
|
||||
- 验证策略:验证集仅真实数据,确保评估不被风格差异干扰。
|
||||
- 推理策略:GPU 默认 ResNet34 + FPN;CPU 小任务可评估单尺度 + 更紧的 NMS。
|
||||
|
||||
---
|
||||
|
||||
## 5. 项目增益(Impact Registry)
|
||||
|
||||
- 训练收敛更稳(Elastic + 程序合成)。
|
||||
- 泛化能力增强(风格域与结构多样性扩大)。
|
||||
- 工程复现性提高(一键管线、配置写回、TB 导出)。
|
||||
- 推理经济性提升(FPN 达标的速度与显存对标)。
|
||||
|
||||
---
|
||||
|
||||
## 6. 附录(Appendix)
|
||||
|
||||
- 一键命令(含扩散目录):
|
||||
|
||||
```zsh
|
||||
uv run python tools/synth_pipeline.py \
|
||||
--out_root data/synthetic \
|
||||
--num 200 --dpi 600 \
|
||||
--config configs/base_config.yaml \
|
||||
--ratio 0.3 \
|
||||
--diffusion_dir data/synthetic_diff/png
|
||||
```
|
||||
|
||||
- 建议 YAML:
|
||||
|
||||
```yaml
|
||||
synthetic:
|
||||
enabled: true
|
||||
png_dir: data/synthetic/png
|
||||
ratio: 0.3
|
||||
diffusion:
|
||||
enabled: true
|
||||
png_dir: data/synthetic_diff/png
|
||||
ratio: 0.1
|
||||
augment:
|
||||
elastic:
|
||||
enabled: true
|
||||
alpha: 40
|
||||
sigma: 6
|
||||
alpha_affine: 6
|
||||
prob: 0.3
|
||||
```
