# Test Runner
|
||
|
||
运行 sanity tests、生成对比图、创建带有视觉比较和解释的综合复现报告。
|
||
|
||
**重要**: 图片对比必须使用 `result-verifier` 子 Agent 进行盲测验证，防止上下文偏见导致误判。
|
||
|
||
## Required Inputs
|
||
|
||
1. `src/` 中的生成代码
|
||
2. `tests/` 中的测试文件
|
||
3. `analysis/reference_plots.py` - 用于对比的参考图生成脚本
|
||
4. `analysis/replication_plan.md` - 复现计划
|
||
|
||
## Required Outputs
|
||
|
||
1. Sanity test 执行结果
|
||
2. `reports/figures/` 中的生成图
|
||
3. `reports/replication_report.md` - 包含图片和解释的对比报告
|
||
|
||
## Workflow
|
||
|
||
### Step 1: Run Sanity Tests
|
||
|
||
```bash
|
||
cd workspace/{paper_name}
|
||
source .venv/bin/activate
|
||
|
||
# 运行 sanity tests（shape、gradient、range 测试）
|
||
pytest tests/ -v --tb=short
|
||
```
|
||
|
||
注意：测试应该通过，但它们只验证基本正确性，不验证精确数值匹配。
|
||
|
||
### Step 2: Generate Replication Figures
|
||
|
||
运行训练/评估并保存图片：
|
||
|
||
```python
|
||
# 示例：生成训练曲线
|
||
plt.figure()
|
||
plt.plot(epochs, losses)
|
||
plt.xlabel('Epoch')
|
||
plt.ylabel('Loss')
|
||
plt.title('Training Loss (Our Replication)')
|
||
plt.savefig('reports/figures/training_loss.png')
|
||
```
|
||
|
||
### Step 3: Compare with Reference (使用盲测验证)
|
||
|
||
**重要**: 不要自己判断图片是否匹配！必须使用 `result-verifier` Agent 进行盲测。
|
||
|
||
对于每一张需要对比的图片，调用 `result-verifier` 子 Agent：
|
||
|
||
```
|
||
Task(
|
||
subagent_type="result-verifier",
|
||
prompt="""
|
||
请验证以下图片对比:
|
||
- 参考图: analysis/reference_images/fig3.png
|
||
- 复现图: reports/figures/fig3.png
|
||
- 图片说明: Figure 3 - S-SE vs Number of Channels
|
||
"""
|
||
)
|
||
```
|
||
|
||
**为什么要盲测验证？**
|
||
1. 你有实现上下文，可能无意中为代码辩护
|
||
2. result-verifier 没有上下文，只看图片客观判断
|
||
3. 防止"代码能跑"就认为"结果正确"的偏见
|
||
|
||
**验证结果处理**:
|
||
- `PASS` → 在报告中标记 ✅ MATCH
|
||
- `WARNING` → 在报告中标记 ⚠️ NEEDS REVIEW，附上验证器的具体问题
|
||
- `FAIL` → 在报告中标记 ❌ FAIL，**必须列出所有失败原因**
|
||
|
||
### Step 4: Generate Report
|
||
|
||
创建 `reports/replication_report.md`，格式如下。
|
||
|
||
## Report Format
|
||
|
||
```markdown
|
||
# {Paper Title} - Replication Report
|
||
|
||
**Date**: {YYYY-MM-DD}
|
||
**Status**: Complete | Partial | Needs Investigation
|
||

|
||
复现结果和关键发现的简要概述。
|
||
|
||
| Aspect | Status |
|
||
|--------|--------|
|
||
| Code runs without errors | ✅ |
|
||
| Model architecture correct | ✅ |
|
||
| Training converges | ✅ |
|
||
| Results comparable to paper | ⚠️ Minor differences |

## 2. Figure Comparisons
|
||
|
||
### Figure 3: Training Loss Curve
|
||
|
||
<table>
|
||
<tr>
|
||
<th>Paper Reference</th>
|
||
<th>Our Replication</th>
|
||
</tr>
|
||
<tr>
|
||
<td><img src="../analysis/reference_images/fig1_training_loss.png" width="400"/></td>
|
||
<td><img src="figures/training_loss.png" width="400"/></td>
|
||
</tr>
|
||
</table>
|
||
|
||
**Comparison Result**: ✅ ACCEPTABLE
|
||
|
||
**Quantitative Comparison**:
|
||
| Metric | Paper (Reference) | Ours | Difference |
|
||
|--------|-------------------|------|------------|
|
||
| Initial loss | ~2.5 | 2.7 | +8% |
|
||
| Final loss | ~0.12 | 0.15 | +25% |
|
||
| Convergence epoch | ~50 | 55 | +10% |
|
||
|
||
**Analysis**:
|
||
训练曲线显示与论文相同的整体趋势。略高的最终损失（0.15 vs 0.12）可能是由于：
|
||
1. 不同的随机种子初始化
|
||
2. 论文中可能未公开的学习率调度
|
||
|
||
**Verdict**: 定性行为匹配。定量差异在复现的可接受范围内。

### Table 2: Test Accuracy
|
||
|
||
| Method | Paper | Ours | Difference | Status |
|
||
|--------|-------|------|------------|--------|
|
||
| Baseline | 91.2% | 90.8% | -0.4% | ✅ MATCH |
|
||
| Proposed | 95.2% | 93.7% | -1.5% | ⚠️ ACCEPTABLE |
|
||
|
||
**Analysis**:
|
||
我们的 proposed 方法达到 93.7% 准确率，而论文为 95.2%。这 1.5% 的差距可能归因于：
|
||
1. 论文中超参数未完全指定
|
||
2. 数据增强细节不清楚

## 3. Core Implementation Explanation
|
||
|
||
### 3.1 Model Architecture
|
||
|
||
```python
|
||
class TransformerBlock(nn.Module):
|
||
"""
|
||
实现论文 Section 3.2 中的 transformer block。
|
||
|
||
关键设计选择：
|
||
- Pre-LayerNorm（遵循论文描述）
|
||
- GELU 激活（论文 Section 3.2.1）
|
||
"""
|
||
def __init__(self, d_model, n_heads, d_ff, dropout=0.1):
|
||
super().__init__()
|
||
self.norm1 = nn.LayerNorm(d_model)
|
||
self.attn = nn.MultiheadAttention(d_model, n_heads, dropout, batch_first=True)
|
||
self.norm2 = nn.LayerNorm(d_model)
|
||
self.ffn = nn.Sequential(
|
||
nn.Linear(d_model, d_ff),
|
||
nn.GELU(),
|
||
nn.Dropout(dropout),
|
||
nn.Linear(d_ff, d_model),
|
||
nn.Dropout(dropout),
|
||
)
|
||
|
||
def forward(self, x):
|
||
# Pre-norm attention
|
||
x = x + self.attn(self.norm1(x), self.norm1(x), self.norm1(x))[0]
|
||
# Pre-norm FFN
|
||
x = x + self.ffn(self.norm2(x))
|
||
return x
|
||
```
|
||
|
||
**实现理由**: 论文在 Section 3.2 中指定了 pre-LayerNorm，这与原始 Transformer 的 post-LayerNorm 设计不同。
|
||
|
||
### 3.2 Loss Function
|
||
|
||
```python
|
||
# Paper Equation (5): Combined loss
|
||
loss = ce_loss + 0.1 * reg_loss
|
||
```
|
||
|
||
**实现理由**: 论文在 Section 4.1 中明确声明 λ=0.1。

## 4. Known Differences & Explanations
|
||
|
||
| Difference | Classification | Explanation |
|
||
|------------|----------------|-------------|
|
||
| Final loss 25% higher | ACCEPTABLE | 随机种子 + 可能未公开的 LR 调度 |
|
||
| Accuracy 1.5% lower | ACCEPTABLE | 论文中超参数细节不完整 |
|
||
| Faster convergence in epochs | EXPLAINABLE | 由于 GPU 内存限制使用了更大的 batch size |
|
||
|
||
### Difference Classifications:
|
||
- **MATCH**: < 2% 相对差异，基本相同
|
||
- **ACCEPTABLE**: 2-10% 差异，可由随机因素解释
|
||
- **EXPLAINABLE**: > 10% 差异，但有明确原因
|
||
- **INVESTIGATE**: > 10% 差异，原因不明
|
||
- **PAPER_ISSUE**: 我们的结果更合理

```
|
||
|
||
## Difference Classification Guidelines
|
||
|
||
**注意**: 以下分类仅适用于**数值差异**。对于**结构性差异**（如坐标轴变量不同、图表类型不同），必须标记为 FAIL，不可使用 ACCEPTABLE。
|
||
|
||
| Classification | Criteria | Action |
|
||
|----------------|----------|--------|
|
||
| **MATCH** | < 2% 相对差异 | 记录并继续 |
|
||
| **ACCEPTABLE** | 2-10% 差异 | 记录并简要解释 |
|
||
| **EXPLAINABLE** | > 10% 但有明确原因 | 详细记录原因 |
|
||
| **INVESTIGATE** | > 10% 且原因不明 | 检查实现是否有 bug |
|
||
| **PAPER_ISSUE** | 我们的结果更合理 | 记录论文错误的证据 |
|
||
|
||
### 结构性问题 = 自动 FAIL
|
||
|
||
以下情况**不可**标记为 ACCEPTABLE：
|
||
- X轴或Y轴变量不同
|
||
- 图表类型不同
|
||
- 曲线/数据系列数量不同
|
||
- Y轴范围差异超过 3 倍
|
||
- 趋势方向相反
|
||
|
||
这些属于**实现错误**，不是"随机种子差异"可以解释的。
