Nullu: Mitigating Object Hallucinations in Large Vision-Language Models via HalluSpace Projection

Recent studies have shown that large vision-language models (LVLMs) often suffer from the issue of object hallucinations (OH). To mitigate this issue, we introduce an efficient method that edits the model weights based on an unsafe subspace, which we call HalluSpace in this paper. With truthful and…
