An Event Metric and an Episode Metric for a Virtual Guide

Abstract

In this paper we introduce a metric to compare events and episodes in the episodic memory system of a virtual agent. The agent, a virtual tour guide based on a belief – desire – intention cognitive architecture, uses his memories to improve the walks around a virtual city. The guide’s past experiences are memorized as events and organized into episodes. Each event is indexed along six dimensions and is comparable on each dimension with a distinct distance function. This is then utilized to measure the similarity between episodes.
