MINDSTORES: Memory-Informed Neural Decision Synthesis for Task-Oriented Reinforcement in Embodied Systems

  • 用自然语言嵌入存储过往经验,形成可检索的思维记忆库。
  • 在MineDojo中比现有方法更有效学习并应用知识,泛化能力更强。
  • 适合需要持续学习的具身智能系统研究者参考。

尽管大型语言模型(LLMs)在具身智能体的零样本规划中展现出潜力,但其无法从经验中学习且难以建立持久的心理模型,限制了其在复杂开放世界环境(如Minecraft)中的鲁棒性。我们提出MINDSTORES,一种基于经验增强的规划框架,使具身智能体能够通过与环境的自然交互构建并利用心理模型。受人类认知模型构建方式启发,该方法通过维护一个包含过往经历的数据库,以支持未来规划迭代。核心创新在于将积累的经验表示为(状态、任务、计划、结果)元组的自然语言嵌入,可被LLM规划器高效检索和推理,从而生成洞察并指导新状态与任务的计划优化。在提供低级控制的MineDojo仿真环境中进行大量实验表明,MINDSTORES在知识学习与应用方面显著优于现有基于记忆的LLM规划方法,同时保持了零样本方法的灵活性与泛化优势,是实现可通过自然经验持续学习的具身智能系统的重要进展。

原文摘要 · Abstract (English)

While large language models (LLMs) have shown promising capabilities as zero-shot planners for embodied agents, their inability to learn from experience and build persistent mental models limits their robustness in complex open-world environments like Minecraft. We introduce MINDSTORES, an experience-augmented planning framework that enables embodied agents to build and leverage mental models through natural interaction with their environment. Drawing inspiration from how humans construct and refine cognitive mental models, our approach extends existing zero-shot LLM planning by maintaining a database of past experiences that informs future planning iterations. The key innovation is representing accumulated experiences as natural language embeddings of (state, task, plan, outcome) tuples, which can then be efficiently retrieved and reasoned over by an LLM planner to generate insights and guide plan refinement for novel states and tasks. Through extensive experiments in the MineDojo environment, a simulation environment for agents in Minecraft that provides low-level controls for Minecraft, we find that MINDSTORES learns and applies its knowledge significantly better than existing memory-based LLM planners while maintaining the flexibility and generalization benefits of zero-shot approaches, representing an important step toward more capable embodied AI systems that can learn continuously through natural experience.
