Layer-Wise Localization and Classification of Hallucinations in Large Language Models

Hallucinations in LLMs: a lifecycle-based survey of causes, detection, mitigation, and prevention

The lifecycle of hallucination in LLMs is a concept that enables building solid frameworks on the control and reliability of LLMs in high-stakes environments, including health, legal, and scientific research. Although previous surveys have primarily focused on detection or mitigation, this survey provides a lifecycle-b...

Layer-wise symbolic attention instability as a diagnostic signal for hallucination in large language models

A unified symbolic, behavioral, and mechanistic framework that connects symbolic triggers with internal failure dynamics in transformer architectures and provides an interpretable basis for diagnosing and stabilizing symbolic reasoning in LLMs is introduced.
