📝 摘要(中文)
多模态模型和代理的出现使得人工智能系统能够更像人类一样从多种模态中学习和与现实世界互动。然而,如何让多模态代理在复杂的异构数据中持续获取有用信息,尤其是在长时间任务和终身学习环境中,仍然是一个重大挑战。为此,本文提出了一个围绕信息形成与表示及其管理适应性的双轴分析框架,旨在有效维护记忆的连续性,适应变化的用户和环境,并通过积累经验优化记忆管理策略。该框架不仅总结了设计模式,还提出了在源保真度与抽象、时间有效性与来源、可恢复证据的基础上演变记忆策略的原则。
🔬 方法详解
问题定义:本文旨在解决多模态代理在复杂异构数据中持续获取有用信息的挑战,现有方法在长时间任务和终身学习环境中表现不足。
核心思路:提出一个双轴分析框架,Axis I关注信息的形成与表示,Axis II关注记忆管理的适应性,旨在通过有效的记忆机制提升多模态代理的性能。
技术框架:框架分为两个主要部分:Axis I描述信息的编码方式(如模态特定嵌入、文本和结构记录等),Axis II则区分三种记忆层次(静态记忆、动态记忆和自我演化记忆),以适应不同的记忆管理需求。
关键创新:最重要的创新在于提出了自我演化记忆的概念,允许代理根据经验不断更新记忆管理策略,这与传统的固定或动态记忆管理方法有本质区别。
关键设计:在设计中,采用了多种信息编码方式以支持后续推理和行动,同时在记忆管理中引入了稳定和演化的策略,以确保记忆的有效性和适应性。

📄 摘要(原文)
Multimodal models and agents have emerged to enable AI systems to learn from and interact with the real world more like humans by integrating information across multiple modalities. However, enabling multimodal agents to continually acquire useful information from complex, heterogeneous multimodal data remains a significant challenge as they move toward long-horizon tasks and lifelong settings. Addressing this challenge requires effective memory mechanisms that can maintain continuity across sessions, adapt to changing users and environments, and refine memory-management policies through accumulated experience. We introduce a two-axis analytical framework for multimodal agent memory structured around two key questions: how multimodal information is formed and represented (Axis I, Formation and Representation), and how its management adapts with accumulated experience (Axis II, Memory Management). Axis I, Formation and Representation, characterizes what information is retained and how it is encoded (e.g., modality-specific embeddings, textual and structured records, latent and parametric representations) to support subsequent reasoning and action. Axis II, Memory Management, distinguishes three tiers: T1 Static Memory reuses fixed memory; T2 Dynamic Memory updates memory through a stable policy; and T3 Self-Evolving Memory updates memory through an evolving policy. Based on this framework, we synthesize recurring design patterns and derive principles for balancing source fidelity with abstraction, maintaining temporal validity and provenance, grounding memory use in recoverable evidence, and evolving memory policies over time. Furthermore, we discuss the challenges and potential future directions for the memory mechanism of multimodal agents.
