Employing Large Language Models (LLM) in various downstream applications such as classification is crucial, especially for smaller companies lacking the expertise and resources required for fine-tuning a model. Fairness in LLMs helps ensure inclusivity, equal representation based on factors such as race, gender and promotes responsible AI deployment. As the use of LLMs has become increasingly prevalent, it is essential to assess whether LLMs can generate fair outcomes when subjected to considerations of fairness. In this study, we introduce a framework outlining fairness regulations aligned with various fairness definitions, with each definition being modulated by varying degrees of abstraction. We explore the configuration for in-context learning and the procedure for selecting in-context demonstrations using RAG, while incorporating fairness rules into the process. Experiments conducted with different LLMs indicate that GPT-4 delivers superior results in terms of both accuracy and fairness compared to other models. This work is one of the early attempts to achieve fairness in prediction tasks by utilizing LLMs through in-context learning.

利用大型语言模型（LLM）在各种下游应用中进行分类等工作至关重要，通过公平性可以确保包容性，基于种族、性别等因素实现平等代表和促进负责任的人工智能部署。本研究引入了一个框架来概述与各种公平性定义相一致的公平性规定，每个定义均由不同程度的抽象调控。我们通过在流程中将公平规则纳入，并使用RAG选择上下文演示来探索上下文学习的配置和过程。通过与不同LLM的实验比较，发现GPT-4在准确性和公平性方面的结果都优于其他模型。本研究是利用LLMs通过上下文学习实现预测任务公平性的早期尝试之一。
