1 Efficiently Implementing Episodic Memory in Soar

Abstract. Endowing an intelligent agent with an episodic memory affords it a multitude of cognitive capabilities that may be crucial to its efficacy. However, implementing a task-independent episodic memory within a cognitive architecture, while maintaining reactivity over long agent lifetimes, requires efficient algorithms and data structures to store and retrieve memories in a potentially monotonically increasing episodic store. This work is a data-driven exploration into efficient methods for implementing an episodic memory in the Soar cognitive architecture. We present results from Soar-EpMem, an efficient, task-independent integration of episodic memory with Soar 9
