Homer: Episodic Memory

Description

• Stores record of all actions , perceptions , and natural language I/O
• Seems to be important requisite for machine consciousness
• Necessary for meaningful dialog and question-answering
• Episodic memory stored in same module as generic memory, but the two memories can be separated by the agent
• Reflective processes monitor and update episodic memory
  • Perform abstraction, selective forgetting, loop detection
  • Implemented as "realizers" that monitor conditions such as "reach", "return", "pass": when one of these events occurs, the agent announces it.
• Planner also contains small episodic memory to aid in backtracking
  • Records activities of planner
  • Erased each time the planner is invoked
  • Uses same functions as general episodic memory, but may contain different data
  • Cannot be inspected through natural language interface
