Episodic Memory
An AI system's ability to store and retrieve events from a user's personal history, particularly referring to the understanding and recall of first-person perspective long-video content in contexts such as wearable devices. It is considered a core capability of intelligent assistants.
Core Facts
Cognitive psychologist Endel Tulving first distinguished episodic memory from semantic memory in his 1972 work 'Episodic and Semantic Memory,' and later incorporated procedural memory into the framework in 1985.
Endel Tulving further subdivided long-term memory into episodic memory and semantic memory.
Persistent memory is typically divided into three levels: short-term working memory, episodic memory, and semantic memory
Timeline (last 90 days)
Developers should avoid mixing episodic memory and semantic memory in the same collection, otherwise relevance ranking during retrieval will be disturbed by noise.
Tool-graph memory is a kind of experiential or episodic memory; unlike parametric knowledge, it is an external retrievable store.
CapMem proposes converting long video content into text captions as a reusable episodic memory medium for long-video episodic reasoning.
Psychologist Endel Tulving divided human memory into episodic memory and semantic memory.
Episodic memory is primarily encoded and stored by the hippocampus in the brain and works in close collaboration with the amygdala, which processes emotions.
