Cross-Task Generalization Between Understanding and Generation in Unified Vision-Language Models: A Controlled Study
TL;DR
Unified vision-language models (VLMs) can enhance both visual understanding and generation through mixed training, but effectiveness varies based on visual space alignment. This study reveals that imbalances in training data can hinder performance.
✦ Why It Matters
Evaluate your training data balance to optimize performance in vision-language tasks today.
Key Takeaways
- Use well-aligned visual spaces for better model performance.
- Monitor data balance between understanding and generation tasks.
- Incorporate generation supervision to enhance visual concept recovery.
- Test mixed training approaches on real-world applications like LLaVA.
How It Works
The study demonstrates that unified VLMs benefit from mixed training by leveraging relationships learned by the base language model across aligned visual spaces. When visual inputs and outputs are closely related, the model can transfer knowledge effectively, enhancing both understanding and generation tasks.
