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)

  • Forgetting · Discrete eviction

    Minmax sampling and edge-aware pruning evict redundant graph nodes. For StreamMeCo, this specifically supports explicit deletion or eviction of stored items of compressed streaming memory graph.
