How experience becomes memory

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

How memory changes (T2 operations)

  • Update · Rule-based update

    During operation, Persode applies fixed-rule insertion or replacement to timestamped events, emotions and preferences; the memory state changes while the governing update policy remains fixed.

  • Consolidation · Experience abstraction

    During operation, Persode applies abstraction of episodes into reusable experience to timestamped events, emotions and preferences; the memory state changes while the governing update policy remains fixed.

  • Consolidation · Episodic / hierarchical summarization

    During operation, Persode applies episodic or hierarchical summarization to timestamped events, emotions and preferences; the memory state changes while the governing update policy remains fixed.
