摘要：
智能体记忆系统必须容纳持续增长的信息，同时支持高效、上下文感知的检索以用于下游任务。抽象对于扩展智能体记忆至关重要，但通常以牺牲特异性为代价，模糊了有效推理所需的细粒度细节。我们引入了Memora，一种和谐的记忆表示，在结构上平衡了抽象和特异性。Memora通过其主要抽象来组织信息，这些抽象索引具体的记忆值，并将相关更新合并为统一的记忆条目，而线索锚点则扩展了跨记忆不同方面的检索访问，并连接相关记忆。基于这种结构，我们采用了一种检索策略，主动利用这些记忆连接来检索超出直接语义相似性的相关信息。理论上，我们证明了标准的检索增强生成（RAG）和基于知识图谱（KG）的记忆系统是我们框架的特例。实验上，Memora在LoCoMo和LongMemEval基准上建立了新的最先进水平，展示了随着记忆规模扩大，更好的检索相关性和推理有效性。
英文摘要：
Agent memory systems must accommodate continuously growing information while supporting efficient, context-aware retrieval for downstream tasks. Abstraction is essential for scaling agent memory, yet it often comes at the cost of specificity, obscuring the fine-grained details required for effective reasoning. We introduce Memora, a harmonic memory representation that structurally balances abstraction and specificity. Memora organizes information via its primary abstractions that index concrete memory values and consolidate related updates into unified memory entries, while cue anchors expand retrieval access across diverse aspects of the memory and connect related memories. Building on this structure, we employ a retrieval policy that actively exploits these memory connections to retrieve relevant information beyond direct semantic similarity. Theoretically, we show that standard Retrieval-Augmented Generation (RAG) and Knowledge Graph (KG)-based memory systems emerge as special cases of our framework. Empirically, Memora establishes a new state-of-the-art on the LoCoMo and LongMemEval benchmarks, demonstrating better retrieval relevance and reasoning effectiveness as memory scales.
