Tree-of-Evidence: Efficient "System 2" Search for Faithful Multimodal Grounding (2026.findings-acl)
Copied to clipboard
| Challenge: | Attention-based methods fail to faithfully represent the model’s decision process when integrating heterogeneous modalities. |
| Approach: | They propose an inference-time search algorithm that frames interpretability as a discrete optimization problem. |
| Outcome: | The proposed algorithm retains over 98% of full-model AUROC with as few as five evidence units and achieves higher decision agreement and lower error than LIME, SHAP, saliency, and concept-bottleneck baselines under sparse budgets. |
