MGRetrieval: Memory-Guided Reflective Retrieval for Long-Term Dialogue Agents

arXiv:2605.27437v1 Announce Type: cross Abstract: Large Language Models (LLMs) have made significant progress in dialogue, yet redundant memory contexts severely limit their effectiveness in long-term dialogue agents. External memory systems have been proposed to improve memory maintenance. However, these systems mainly rely on one-shot retrieval, which limits their ability to retrieve sufficient and relevant evidence. Although recent methods introduce reflection into retrieval, their retrieval paths are generated by the LLM from limited evidence, leading to unstable retrieval and additional l

Why this matters
Why now

The paper addresses a core limitation of current Large Language Models (LLMs) in long-term dialogue context, which is becoming increasingly critical as agentic systems evolve.

Why it’s important

Improving memory and retrieval for LLMs is crucial for the development of stable, effective, and autonomous AI agents capable of sustained interaction and complex tasks.

What changes

This research proposes a method to make AI agents' memory retrieval more accurate and reflective, moving beyond one-shot retrieval limitations.
