  • 构建结构化-向量-图谱三合一的记忆体系,分层管理短期、中期和长期记忆。
  • 在长时交互中实现记忆选择性调用、动态修订与证据归属,准确率提升显著。
  • 适合需要长期记忆与个性化决策的AI系统,如智能助手与自主代理。

长期运行的AI智能体需要跨交互保持连续性,但仅扩展提示窗口无法实现。智能体必须保留有用的历史经验,能选择性检索,区分个人上下文与外部证据,并在情境变化时更新记忆。本文提出一种双轴记忆架构:表示轴涵盖结构化记录、向量表征与图关系;时间轴涵盖短期痕迹、中期抽象与长期语义承诺。核心设计约束是同步的结构-向量-图记忆机制:结构化记录决定可用性,向量表征支持召回,图关系在门控上下文投影前判定支持、矛盾与覆盖关系。核心主张是可靠个性化本质上是记忆设计问题:有效记忆应结构化、选择性暴露、持续整合,并带有认知标签,而非作为未区分的对话历史存储。除框架外,我们实现了一个轻量级原型,包含结构化记录、向量检索、时间策略与基于图的修订机制。该原型在受控的长期交互场景中,通过预生成阶段的记忆选择、修订、边界控制与证据归因,验证了核心机制的有效性。

原文摘要 · Abstract (English)

Long-lived AI agents require continuity across interactions, but continuity cannot be obtained by simply extending the prompt window. An agent must preserve useful prior experience, retrieve it selectively, distinguish personal context from external evidence, and revise memory when the underlying situation changes. We propose an architectural memory substrate organized along two orthogonal axes: a representational axis spanning structured records, vector representations, and graph relations; and a temporal axis spanning short-term traces, medium-term abstractions, and long-term semantic commitments. Its key design constraint is synchronized structured-vector-graph memory: structured records govern eligibility, vector representations support recall, and graph relations adjudicate support, contradiction, and supersession before gated context projection. Its central claim is that reliable personalization is a memory design problem: useful memory is structured, selectively exposed, continuously consolidated, and epistemically labeled rather than stored as undifferentiated conversation history. Beyond the framework, we instantiate MRMS as a lightweight prototype implementing structured records, vector retrieval, temporal policies, and graph-based revision. The prototype exercises the core substrate mechanisms through pre-generation memory selection, revision, boundary enforcement, and evidence attribution under controlled long-lived interaction scenarios with explicit evidence requirements.
