How experience becomes memory

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

  1. Persistent object instances

How memory changes (T2 operations)

  • Update · Rule-based update

    During operation, Where Did I Leave My Glasses? applies fixed-rule insertion or replacement to Persistent object instances; the memory state changes while the governing update policy remains fixed.

  • Revision · Rule-based state correction

    During operation, Where Did I Leave My Glasses? applies fixed-rule correction of stored state to Persistent object instances; the memory state changes while the governing update policy remains fixed.

  • Revision · Evidence-weighted belief revision

    During operation, Where Did I Leave My Glasses? applies evidence-weighted revision of stored belief or confidence to Persistent object instances; the memory state changes while the governing update policy remains fixed.
