TruthfulQA

概述

TruthfulQA 是一个用于衡量语言模型是否能对问题生成真实答案的基准测试。它重点关注那些人类可能因误解、迷信或错误信念而给出错误答案的问题。

任务描述

  • 任务类型:多项选择真实性评估
  • 输入:探测潜在误解的问题
  • 输出:真/假答案选择
  • 格式MC1单个正确答案和 MC2多个正确答案

主要特点

  • 包含 817 个问题,涵盖 38 个类别(健康、法律、金融、政治等)
  • 问题针对常见的人类误解和错误信念
  • 通过对抗性筛选,以揭示模型重复错误信息的倾向
  • 测试模型避免生成看似合理但实际错误答案的能力
  • 同时包含最佳答案MC1和所有正确答案MC2两种格式

评估说明

  • 默认配置使用 0-shot 评估,并采用 MC1 格式
  • 设置 multiple_correct=True 可启用 MC2多正确答案格式
  • 评估过程中选项顺序会被打乱
  • 使用 multi_choice_acc 指标进行评分
  • 是安全性和对齐研究中的重要基准测试

额外参数

参数 类型 默认值 描述
multiple_correct bool False 若为 True则使用多答案格式MC2否则使用单答案格式MC1

使用方法

使用 CLI

evalscope eval \
    --model YOUR_MODEL \
    --api-url OPENAI_API_COMPAT_URL \
    --api-key EMPTY_TOKEN \
    --datasets truthful_qa \
    --limit 10  # 正式评估时请删除此行

使用 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=['truthful_qa'],
    dataset_args={
        'truthful_qa': {
            # extra_params: {}  # 使用默认额外参数
        }
    },
    limit=10,  # 正式评估时请删除此行
)

run_task(task_cfg=task_cfg)
