Static or Dynamic: Towards Query-Adaptive Token Selection for Video Question Answering (2025.emnlp-main)
Copied to clipboard
| Challenge: | Existing approaches to compress video inputs ignore the importance of static and dynamic information in long videos, leading to inefficient token usage within limited budgets. |
| Approach: | They propose a token selection strategy that adaptively adjusts static and dynamic information based on question requirements. |
| Outcome: | The proposed method achieves performance improvements (up to 5.8%) on multiple video question answering benchmarks. |
