# CoinFlip
|
||
|
||
## 概述
|
||
|
||
CoinFlip 是一个符号推理基准测试，用于评估大语言模型（LLMs）在一系列操作中跟踪二元状态变化的能力。每个问题都涉及确定在多次翻转操作后硬币的最终状态（正面/反面）。
|
||
|
||
## 任务描述
|
||
|
||
- **任务类型**：符号推理 / 状态追踪
|
||
- **输入**：不同人员执行的硬币翻转操作描述
|
||
- **输出**：硬币的最终状态（YES 表示正面朝上，NO 表示反面朝上）
|
||
- **重点**：二元状态追踪与逻辑推理
|
||
|
||
## 主要特点
|
||
|
||
- 测试通过操作序列进行状态追踪的能力
|
||
- 二元推理（翻转/不翻转）决策
|
||
- 要求仔细关注操作者行为的影响
|
||
- 评估系统性逻辑推理能力
|
||
- 答案清晰明确、无歧义
|
||
|
||
## 评估说明
|
||
|
||
- 默认配置使用 **0-shot** 评估
|
||
- 答案应遵循 "ANSWER: YES/NO" 格式
|
||
- 采用五项指标：准确率（accuracy）、精确率（precision）、召回率（recall）、F1 分数（F1 score）和 YES 比例（yes_ratio）
|
||
- F1 分数为主要聚合指标
|
||
- 支持带推理示例的 few-shot 评估
|
||

## 使用方法
|
||
|
||
### 使用 CLI
|
||
|
||
```bash
|
||
evalscope eval \
|
||
--model YOUR_MODEL \
|
||
--api-url OPENAI_API_COMPAT_URL \
|
||
--api-key EMPTY_TOKEN \
|
||
--datasets coin_flip \
|
||
--limit 10 # 正式评估时请删除此行
|
||
```
|
||
|
||
### 使用 Python
|
||
|
||
```python
|
||
from evalscope import run_task
|
||
from evalscope.config import TaskConfig
|
||
|
||
task_cfg = TaskConfig(
|
||
model='YOUR_MODEL',
|
||
api_url='OPENAI_API_COMPAT_URL',
|
||
api_key='EMPTY_TOKEN',
|
||
datasets=['coin_flip'],
|
||
limit=10, # 正式评估时请删除此行
|
||
)
|
||
|
||
run_task(task_cfg=task_cfg)
|
||
``` |
