📝 摘要(中文)

大型语言模型代理从单一任务执行到长期自主操作的演变,突显了将持续经验转化为可重用知识的关键挑战。为此,本文提出了Hippocam,一个分层记忆与持续学习架构。Hippocam借鉴了人类记忆的两个特征:认知过程选择性地保持与当前目标相关的信息,而长期记忆则通过重复巩固逐渐形成。Hippocam将代理的持续工作结构化为嵌套意图,当前意图的上下文保持集中,而已完成的意图则被巩固为后续工作所需的任务相关结果和状态。通过这种动态的使用与不使用的记忆机制,Hippocam将工作上下文、长期记忆、知识积累和技能学习连接在一个不断演变的经验过程中。

🔬 方法详解

问题定义:本文旨在解决大型语言模型代理在长期记忆和经验重用方面的不足,现有方法难以有效整合历史经验,导致知识积累效率低下。

核心思路:Hippocam的核心思路是模仿人类记忆的特性,通过分层意图结构和递归巩固机制,使代理能够选择性地维护与当前目标相关的信息,并逐步巩固长期记忆。

技术框架:Hippocam的整体架构包括两个主要模块:嵌套意图结构和递归前缀巩固机制。嵌套意图结构用于组织当前工作,而递归巩固机制则用于将历史经验转化为抽象知识。

关键创新:Hippocam的创新在于其动态的使用与不使用的记忆机制,使得代理能够在不更新参数的情况下,通过自身经验不断学习和进化,这与现有方法的静态记忆处理方式有本质区别。

关键设计:在设计中,Hippocam采用了递归巩固算法,确保历史经验的逐步抽象化,同时保留原始交互以便在需要时恢复细节。

📄 摘要(原文)

The evolution of Large Language Model agents from single-task execution to long-term autonomous operation highlights the critical challenge of transforming continuous experiences into reusable knowledge. To address this, we propose Hippocam, a hierarchical memory and continual learning architecture. Hippocam draws inspiration from two characteristics of human memory: cognitive processes selectively maintain information relevant to current goals, while long-term memories form gradually through repeated consolidation. Accordingly, Hippocam structures an agent's ongoing work as nested intents. The active context remains centered on the current intent, while completed intents are consolidated into the task-relevant outcomes and state needed for subsequent work, rather than carrying forward their full working details. Concurrently, a recursive prefix consolidation mechanism repeatedly consolidates earlier history, causing long-unused experiences to become increasingly abstract. Original interactions are preserved, allowing the agent to progressively recover finer-grained details through the hierarchy and stop once sufficient information is available. Crucially, when past experiences are recalled and reintegrated into active work, they undergo subsequent consolidation alongside new experiences, thereby being reinforced, supplemented, and updated. Through this memory dynamic of use and disuse, Hippocam connects working context, long-term memory, knowledge accumulation, and skill learning within a single continuously evolving experiential process. This enables agents to learn and evolve capabilities through their own experiences without parameter updates.
