Detecting Hallucination in LLMs: Tracing the Topological Signatures of Impaired Context Sharing

arXiv:2609.21096v1 Announce Type: new Abstract: In this work, we examine the topology of information flow patterns within attention graphs to effectively distinguish hallucinated from non-hallucinated responses. We analyze the Forman-Ricci curvature to identify structural patterns indicating information bottlenecks in attention graphs. We then introduce a method that captures both semi-local and g

What this event means by reading role—not a longer recap.

  • BuilderBuilders could add a single-pass attention-graph curvature check as a cheap hallucination guardrail, though no code or API is released yet.
  • ResearcherResearchers get a curvature-based, single-pass alternative to multi-response hallucination baselines, with evidence that over-squashing in the final layer track
