Perceptual Hallucination in Vision–Language Models: Definition, Analysis and Verification (2026.findings-acl)
Copied to clipboard
| Challenge: | Recent advances in large language models (LLMs) have dramatically improved text understanding and generation capabilities. |
| Approach: | They define perceptual hallucination as the phenomenon where VLMs generate information as if perceived, despite absent or damaged visual evidence. |
| Outcome: | The proposed model reduces hallucination exposure by 36% on average, with reductions of up to 88%. |
