Episodic Memory (Per-Session History)
Per-conversation logs of what happened, indexed by time and session id.
Three Types of Memory
Inspired by cognitive science, agent memory is usually split into three kinds:
- Episodic — what happened (this conversation, last week's session)
- Semantic — facts about the world / user
- Procedural — skills (successful action sequences)
This lesson covers episodic.
What Is Episodic Memory?
Episodic memory stores specific events with timestamps and context. For an agent, this is the per-session conversation log.
It is the most basic form of memory and the easiest to build.
