UnverifiedAs interactions accumulate, raw historical records will exceed the model's context window limit, requiring periodic summarization or tiered storage for memory compression.78% similarUnverifiedMemory decay refers to the truncation or compression of historical information once it exceeds the context window, significantly reducing an agent's ability to track its own inventory, completed progress, and outstanding commitments.74% similarUnverifiedIf the memory store is full of duplicate, outdated, or mutually contradictory entries, the retrieval results will contain large amounts of low-value information, crowding out context space and even misleading the model, which is context pollution.72% similarUnverifiedState-drift describes a situation where an Agent's memory system recorded information at some point in time, and after the facts in the world changed, the system still retrieves and acts on the old record with full confidence, while the retrieval pipeline itself is not at fault.71% similarUnverifiedWhen vector retrieval recalls information, the system converts the current question into a vector, looks up in the database the several historical records with the closest distance, and injects them into the prompt.70% similar
