GEASS: Gated Evidence-Adaptive Selective Caption Trust for Vision-Language Models

Jiashen Ding, Shuoyang Zhang, Zeshang Li

GEASS lets vision-language models decide per query how much of a self-generated caption to trust, cutting hallucinations.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Experiments on POPE and HallusionBench across four VLMs show that GEASS consistently improves over vanilla inference and contrastive decoding, with only two extra forward passes per query.

C2weakest assumption

That the combination of clean-path confidence and entropy reduction reliably identifies when and how much caption content is useful without discarding beneficial information or introducing new selection bias on a per-query basis.

C3one line summary

GEASS selectively gates and weights self-generated captions using confidence and entropy to reduce object hallucinations in VLMs, outperforming vanilla inference and contrastive decoding on POPE and HallusionBench.
