Naive Reverse Grouper

ASecurity

将批处理的样本拆分为独立样本。当用户提到样本拆分、拆分批次、批处理展开、反向分组等需求时使用此skill。 即使用户没有明确说出"拆分",只要任务涉及将批处理数据(字段值为数组)展开为独立样本,就应该使用此skill。

# Naive Reverse Grouper

将批处理的样本拆分为独立样本。

本SKILL使用依赖data_juicer,请在调用前安装好python环境并安装data_juicer,你可用同以下指令进行安装:
```
pip install py-data-juicer
```

## 核心参数

| 参数 | 类型 | 必填 | 默认值 | 说明 |
|------|------|------|--------|------|
| input_path | string | 是 | - | 输入JSON文件路径 |
| output_path | string | 是 | - | 输出JSON文件路径 |
| export_path | string | 否 | - | 可选,导出批次元数据到JSONL文件 |

## 使用方法

```bash
python scripts/run_naive_reverse_grouper.py --input_path <input_path> --output_path <output_path> [--export_path <path>]
```

## 实现原理

参照测试代码 test_naive_reverse_grouper.py 中的 `_run_helper` 函数:

```python
# 1. 将批次化样本列表转换为Dataset
dataset = Dataset.from_list(samples)

# 2. 初始化算子并执行(无参数,或传入 export_path)
op = NaiveReverseGrouper()
new_dataset = op.run(dataset)
```

## 输入输出格式

### 输入格式 (JSON数组,字段值为数组)

```json
[
  {"text": ["Sample 1", "Sample 2", "Sample 3"]}
]
```

### 输出格式 (JSON数组,拆分为独立样本)

```json
[
  {"text": "Sample 1"},
  {"text": "Sample 2"},
  {"text": "Sample 3"}
]
```

## 示例

### 示例1:基本拆分

```bash
python scripts/run_naive_reverse_grouper.py --input_path example_input.json --output_path output.json
```

### 示例2:同时导出批次元数据

```bash
python scripts/run_naive_reverse_grouper.py --input_path example_input.json --output_path output.json --export_path batch_meta.jsonl
```

## 注意事项

- 此算子无需额外参数(export_path可选)
- 输入样本的字段值为数组形式
- 输出会将数组展开为多个独立样本
- 如果传入 export_path,会将批次元数据导出为 JSONL 格式
