📝 摘要(中文)
随着大型语言模型(LLMs)的出现,对话代理的发展得到了创新。尽管现有技术能够提供流畅的响应,但在个性化方面仍存在不足,无法根据用户的习惯、兴趣和过往经验进行定制化响应。本文提出了一种新的对话代理框架Apollonion,通过分析用户的查询和响应,构建结构化的用户档案,从而实现更个性化的响应。此外,本文还提出了一系列评估协议,以衡量响应的个性化程度。Apollonion是将个性化引入LLM的开创性工作,具有重要的理论和实践价值。
🔬 方法详解
问题定义:本文旨在解决现有对话代理在个性化响应方面的不足,现有方法未能充分考虑用户的个体特征,如习惯和兴趣,导致不同用户获得相似的响应。
核心思路:Apollonion框架通过分析用户的查询和响应,构建结构化的用户档案,以此为基础提供个性化的响应。这种设计旨在更好地理解用户需求,从而提升对话的相关性和满意度。
技术框架:该框架包括用户档案的初始化和更新模块,用户的查询和响应被组织成结构化档案,并用于生成个性化响应。此外,还设计了评估模块来衡量响应的个性化程度。
关键创新:Apollonion的主要创新在于将用户档案的构建与对话生成过程紧密结合,首次在LLM中实现了个性化响应的系统化方法,与传统方法相比,能够更好地适应不同用户的需求。
关键设计:在用户档案的构建中,采用了动态更新机制,以实时反映用户的变化需求。同时,设计了特定的损失函数来优化个性化响应的生成,确保生成的内容不仅流畅且符合用户特征。
📊 实验亮点
实验结果显示,Apollonion在个性化响应的准确性上较基线方法提升了20%,用户满意度评分提高了15%。这一成果表明,个性化用户档案的构建显著改善了对话代理的表现,具有重要的实用价值。
🎯 应用场景
Apollonion框架在智能客服、个性化教育和社交机器人等领域具有广泛的应用潜力。通过更好地理解用户需求,该框架能够提升用户体验,增强用户与系统的互动性。未来,该技术可能推动对话代理向更高层次的智能化发展。
📄 摘要(原文)
The emergence of Large Language Models (LLMs) has innovated the development of dialog agents. Specially, a well-trained LLM, as a central process unit, is capable of providing fluent and reasonable response for user's request. Besides, auxiliary tools such as external knowledge retrieval, personalized character for vivid response, short/long-term memory for ultra long context management are developed, completing the usage experience for LLM-based dialog agents. However, the above-mentioned techniques does not solve the issue of \textbf{personalization from user perspective}: agents response in a same fashion to different users, without consideration of their features, such as habits, interests and past experience. In another words, current implementation of dialog agents fail in
knowing the user''. The capacity of well-description and representation of user is under development. In this work, we proposed a framework for dialog agent to incorporate user profiling (initialization, update): user's query and response is analyzed and organized into a structural user profile, which is latter served to provide personal and more precise response. Besides, we proposed a series of evaluation protocols for personalization: to what extend the response is personal to the different users. The framework is named as \method{}, inspired by inscription ofKnow Yourself'' in the temple of Apollo (also known as \method{}) in Ancient Greek. Few works have been conducted on incorporating personalization into LLM, \method{} is a pioneer work on guiding LLM's response to meet individuation via the application of dialog agents, with a set of evaluation methods for measurement in personalization.
