Switching Heads and Softening Tokens: Turnkey Solutions to Visually Grounded Document QA (2026.findings-acl)
Copied to clipboard
| Challenge: | Document Question Answering lacks robust, end-to-end solutions capable of handling complex, multi-answer queries without reliance on ad-hoc processing. |
| Approach: | They propose a single-head architecture where coordinates are represented as special tokens within the unified vocabulary. |
| Outcome: | The proposed architectures improve visual grounding but lack spatial precision bound by discretization. |
