Background
The purpose of this thesis project is to investigate long-term memory mechanisms for embodied Large Language Model (LLM) agents, with a particular focus on episodic memory, memory consolidation, and forgetting. While existing agent memory systems primarily rely on retrieval-based approaches, recent research suggests that long-term intelligent behavior requires mechanisms that transform episodic experiences into more persistent, structured, and reusable knowledge.
Embodied LLM agents operating in dynamic environments must be able to remember past experiences, generalize from them, and adapt their behavior over extended periods of time. Although retrieval-based memory systems have demonstrated promising results, they often struggle with challenges related to scalability, interference, long-term retention, and effective knowledge abstraction. Drawing inspiration from human memory systems, approaches based on memory consolidation may enable agents to convert short-term experiences into more durable representations that support reasoning and decision-making across longer time horizons.
Description of the Thesis Project
The work will focus on evaluating how different strategies for storing, retrieving, consolidating, and forgetting experiences affect an embodied agent's ability to perform tasks in dynamic environments. Particular emphasis will be placed on understanding the trade-offs between memory capacity, retention, recall accuracy, interference resistance, and behavioral adaptation. The thesis will include a literature review of memory mechanisms for embodied and LLM-based agents, the implementation of a memory architecture supporting long-term memory consolidation, and evaluation in a simulated environment. Experiments will assess memory performance and agent behavior using benchmarks measuring recall accuracy, retention, interference resistance, spatial-temporal reasoning, and adaptation to changing conditions. The goal is to identify principles for scalable long-term memory systems that improve both memory performance and agent decision-making.
The thesis will be carried out together with Underwater Systems and the Mission Autonomy group at Saab Dynamics, which works on agentic intelligence and advanced autonomy solutions for future unmanned systems.
