Constructing coherent spatial memory in LLM agents through graph rectification

arXiv:2510.04195v2 Announce Type: replace Abstract: Given a map description through global traversal navigation instructions, an LLM can often infer the implicit spatial layout and answer user queries by providing shortest paths. However, such context-dependent querying becomes incapable as environments grow larger, motivating the need for incremental map construction that builds a complete topological graph from stepwise observations. We propose LLM-MapRepair, a framework for LLM-driven construction and map repair, designed to detect, localize, and correct structural inconsistencies in increm

Why this matters
Why now

The increasing complexity of AI agent applications in real-world environments necessitates robust spatial reasoning and memory, pushing research towards more coherent and scalable solutions.

Why it’s important

Improving LLM spatial memory and error correction is critical for developing autonomous agents capable of navigating and understanding large, dynamic environments, crucial for tasks ranging from logistics to robotics.

What changes

LLMs can move beyond simple context-dependent querying to incrementally build and repair complex topological graphs for spatial understanding, enabling more sophisticated and reliable agent behaviors.
