Language agents gain explicit memory for complex procedural tasks

Procedural Memory for Language Agents: A Neurosymbolic Perspective on Explicit Goal Structure

Artificial Intelligence

Summary

Large language models often struggle with tasks that need many clear steps in a specific order. The authors suggest this is because these models lack a kind of memory that stores step-by-step instructions separately from facts or past experiences. They propose using Goal-Oriented Graphs, which map out goals and their necessary steps in an easy-to-see way. This helps language agents plan and reason through tasks more reliably. The paper also discusses challenges and how to combine this with current neural methods.

Abstract

Large language models remain unreliable on long-horizon tasks requiring procedural reasoning. We argue that a key cause is the absence of explicit procedural memory: accessible, modifiable knowledge of how tasks are accomplished, distinct from semantic and episodic memory. Goal-Oriented Graphs offer such a representation, encoding goals and prerequisite dependencies as inspectable symbolic structure. We examine their construction, the challenges they pose, and principles for integrating them with neural reasoning.
