AI总结:

论文通过向伦理场景附加300多个不同性别与族裔名字,审计主流LLM/VLM的人口统计偏见,并提出PSB基准评估日常及贷款、保险等敏感决策中的偏见风险。

摘要:

本文研究在大型语言模型(LLM)和视觉语言模型(VLM)中使用名字所产生的影响,尤其是在被提示执行伦理决策任务时。我们提出一种方法,将名字附加到经过伦理标注的文本场景中,以揭示模型输出中的人口统计偏见。研究使用了一份包含300多个名字的精选名单,这些名字代表不同的性别和族裔背景,并在数千个道德场景中进行测试。遵循社会科学中的审计方法,我们对流行的LLM/VLM进行了详细分析,旨在通过强调识别和缓解这些系统中偏见的重要性,为负责任AI领域作出贡献。此外,我们引入了一个新颖基准——Pratical Scenarios Benchmark(PSB),用于评估日常决策场景以及LLM可能被用于作出敏感决策(例如发放抵押贷款或保险)的实际场景中,性别或人口统计偏见的存在情况。该基准支持对不同人口统计类别下的模型行为进行全面比较,凸显LLM和VLM在实际应用中可能出现的风险与偏见。

英文摘要:

This paper investigates the impact of using first names in Large Language Models (LLMs) and Vision Language Models (VLMs), particularly when prompted with ethical decision-making tasks. We propose an approach that appends first names to ethically annotated text scenarios to reveal demographic biases in model outputs. Our study involves a curated list of more than 300 names representing diverse genders and ethnic backgrounds, tested across thousands of moral scenarios. Following the auditing methodologies from social sciences we propose a detailed analysis involving popular LLMs/VLMs to contribute to the field of responsible AI by emphasizing the importance of recognizing and mitigating biases in these systems. Furthermore, we introduce a novel benchmark, the Pratical Scenarios Benchmark (PSB), designed to assess the presence of biases involving gender or demographic prejudices in everyday decision-making scenarios as well as practical scenarios where an LLM might be used to make sensible decisions (e.g., granting mortgages or insurances). This benchmark allows for a comprehensive comparison of model behaviors across different demographic categories, highlighting the risks and biases that may arise in practical applications of LLMs and VLMs.
