VIB-Probe: Detecting and Mitigating Hallucinations in Vision-Language Models via Variational Information Bottleneck
Researchers propose VIB-Probe, a novel framework using Variational Information Bottleneck theory to detect and mitigate hallucinations in Vision-Language Models by analyzing internal attention mechanisms. The method identifies specific attention heads responsible for truthful generation and introduces an inference-time intervention strategy that outperforms existing detection baselines.
