How experience becomes memory

Each path is one memory component, traced from what is stored to how it is found again.

  1. object/user-pattern memory

    3. Retrieved bySimilarity search, Structure traversal, Planner / tool-assisted retrieval

    Past interactions become personalized object and routine memory entries. agents retrieve object-semantic and user-pattern memories for planning.Full-paper method / memory representation and retrieval · PDF p. 18 · Figure 1 / method overview

How memory changes (T2 operations)

  • Update · Rule-based update

    During operation, MEMENTO Personalization applies fixed-rule insertion or replacement to object/user-pattern memory; the memory state changes while the governing update policy remains fixed.

  • Consolidation · Episodic / hierarchical summarization

    During operation, MEMENTO Personalization applies episodic or hierarchical summarization to object/user-pattern memory; the memory state changes while the governing update policy remains fixed.
