Does the Question Really Matter? Training-Free Data Selection for Vision-Language SFT
🤖AI Summary
Researchers propose CVS, a training-free method for selecting high-quality vision-language training data that requires genuine cross-modal reasoning. The method achieves better performance using only 10-15% of data compared to full dataset training, while reducing computational costs by up to 44%.
Key Takeaways
- →CVS method identifies samples requiring genuine vision-language reasoning by measuring how questions alter answer validity assessment.
- →Achieves 3.5-4.8% performance improvement over full-data training using only 10-15% of selected data.
- →Reduces computational costs by 17.3-44.4% compared to existing data selection methods COINCIDE and XMAS.
- →Method is training-free and uses frozen vision-language models as evaluators to filter low-quality samples.
- →Successfully validated on Vision-Flan and Cauldron datasets, showing robustness across different data types.
