PaLM2-VAdapter introduces an efficient vision-language adapter architecture that leverages a progressively aligned tiny language model, significantly enhancing the performance of Large Vision-Language Models. This approach achieves state-of-the-art results on diverse image and video tasks with approximately 30-70% fewer total parameters and converges up to three times faster than previous methods.
Key insights
- A small, progressively aligned language model can serve as a highly effective and efficient vision-language adapter, outperforming traditional architectures.
- A two-stage training strategy, first aligning the tiny language model as a decoder and then as an adapter, is crucial for optimal performance.
- While a language model forms the core adapter, a lightweight cross-attention module is still essential for initial, efficient visual-to-linguistic feature fusion.
