📝 摘要(中文)
在动态环境中,现有的环境知识迅速过时,导致自主系统的内部模型与实际操作环境之间存在差距,从而限制了决策的有效性。为了解决这一问题,本文提出了LUCIFER框架,该框架将层次化决策架构、强化学习和大型语言模型整合为一个统一系统。LUCIFER不仅作为上下文提取器,将人类利益相关者的输入转化为影响决策的领域感知表示,还作为零样本探索促进者,指导代理在探索过程中的行动选择。实验结果表明,LUCIFER在探索效率和决策质量上均优于传统的目标条件策略,展示了基于上下文的决策潜力。
🔬 方法详解
问题定义:本文旨在解决自主系统在动态环境中因环境知识过时而导致的决策失效问题。现有方法通常无法有效整合人类的上下文知识,导致决策质量下降。

📄 摘要(原文)
In dynamic environments, the rapid obsolescence of pre-existing environmental knowledge creates a gap between an agent's internal model and the evolving reality of its operational context. This disparity between prior and updated environmental valuations fundamentally limits the effectiveness of autonomous decision-making. To bridge this gap, the contextual bias of human domain stakeholders, who naturally accumulate insights through direct, real-time observation, becomes indispensable. However, translating their nuanced, and context-rich input into actionable intelligence for autonomous systems remains an open challenge. To address this, we propose LUCIFER (Language Understanding and Context-Infused Framework for Exploration and Behavior Refinement), a domain-agnostic framework that integrates a hierarchical decision-making architecture with reinforcement learning (RL) and large language models (LLMs) into a unified system. This architecture mirrors how humans decompose complex tasks, enabling a high-level planner to coordinate specialised sub-agents, each focused on distinct objectives and temporally interdependent actions. Unlike traditional applications where LLMs are limited to single role, LUCIFER integrates them in two synergistic roles: as context extractors, structuring verbal stakeholder input into domain-aware representations that influence decision-making through an attention space mechanism aligning LLM-derived insights with the agent's learning process, and as zero-shot exploration facilitators guiding the agent's action selection process during exploration. We benchmark various LLMs in both roles and demonstrate that LUCIFER improves exploration efficiency and decision quality, outperforming flat, goal-conditioned policies. Our findings show the potential of context-driven decision-making, where autonomous systems leverage human contextual knowledge for operational success.
