UnverifiedAgent memory retrieval usually adopts a hybrid strategy: vector retrieval captures semantic similarity, metadata filtering narrows the candidate set, and a reranking model performs the final ranking based on task context and preference weights.74% similarUnverified向量检索的效果高度依赖于分块策略，常用方法包括固定长度分块、基于语义的分块以及递归分块73% similarUnverifiedAblation experiments show that combining reasoning with retrieval yields the best performance, with the two forming a complementary relationship.71% similarUnverifiedIn multi-hop reasoning scenarios, each hop's retrieval should incrementally supplement based on the conclusions of the previous hop, and the decision model can explicitly track the known information set to avoid redundant recall.70% similarUnverifiedA common engineering strategy is a cascaded model—first using a lightweight, fast model to filter simple forms, then routing difficult cases to a heavier, more precise model.70% similar
