Bridging the Visual Gap: Fine-Tuning Multimodal Models with Knowledge-Adapted Captions (2025.naacl-long)
Copied to clipboard
| Challenge: | Recent work focuses on training vision-language models with long, detailed image captions, but small-scale VLMs struggle to balance the richness of these captions with the risk of hallucinations. |
| Approach: | They propose an evaluation framework that breaks down generated captions into individual propositions, assessing each in isolation. |
| Outcome: | The proposed framework outperforms baselines in both automatic metrics and human evaluations on small-scale vision-language models with long, detailed captions. |
Mitigating Open-Vocabulary Caption Hallucinations (2024.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods for image captioning ignore the long-tailed nature of hallucinations . a new framework is proposed to address hallucines in image captions in the open-vocabulary setting . |
| Approach: | They propose a framework to address hallucinations in image captioning in the open-vocabulary setting. |
| Outcome: | The proposed framework surpasses the CHAIR benchmark in diversity and accuracy in open-vocabulary captioning. |
