VisNec: Measuring and Leveraging Visual Necessity for Multimodal Instruction Tuning
arXiv – CS AI|Mingkang Dong, Hongyi Cai, Jie Li, Sifan Zhou, Bin Ren, Kunyu Peng, Yuqian Fu||6 views
🤖AI Summary
Researchers developed VisNec, a framework that identifies which training samples truly require visual reasoning for multimodal AI instruction tuning. The method achieves equivalent performance using only 15% of training data by filtering out visually redundant samples, potentially making multimodal AI training more efficient.
Key Takeaways
- →VisNec framework measures visual necessity in multimodal training by comparing predictive loss with and without visual context.
- →Training on only 15% of LLaVA-665K dataset selected by VisNec achieves 100.2% of full-data performance across 10 benchmarks.
- →The method identifies and removes visually redundant samples that can be solved from text alone.
- →On Vision-Flan-186K dataset, the approach not only reduces data size but surpasses full-data training by 15.8%.
- →The framework combines visual necessity scoring with semantic clustering to preserve task diversity.
