The authors trace this object hallucination to two sources: statistical bias from co-occurrence patterns in pretraining data, and the language priors of the underlying LLM decoder. They show that making the image less clear… 2. **[VideoLLaMA 2: Advancing Spatial-Temporal Modeling and Audio Understanding in Video-LLMs](https://md.research.elamur.ai/free/en/papers/cheng-2024-videollama-2-advancing-spatial-temporal/)** *(2024 · 118 citations)* Video-LLMs lag behind image-focused multimodal models because they fuse information across frames poorly and usually ignore the soundtrack. VideoLLaMA 2, from DAMO Academy (Alibaba Group), tackles both weaknesses while keeping the modular two-branch layout of the original VideoLLaMA. ## All works 3 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1. **[Mitigating Object Hallucinations in Large Vision-Language Models through Visual Contrastive Decoding](https://md.research.elamur.ai/free/en/papers/leng-2023-mitigating-object-hallucinations-large-vision/) [IEEE Computer Society Conference on Computer Vision and Pattern Recognition](https://md.research.elamur.ai/free/en/venues/ieee-computer-society-conference-on-computer-vision-and-pattern-recognition/)**Sicong Leng, Hang Zhang, Guanzheng Chen, et al.*2023 · 322 citations* 2.
