Bridging the Dynamic Perception Gap: Training-Free Draft Chain-of-Thought for Dynamic Multimodal Spatial Reasoning (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Existing methods for dynamic spatial reasoning are limited to text or static visual domains . |
| Approach: | They propose a framework that augments textual reasoning chains with dynamic visual drafts . |
| Outcome: | The proposed framework outperforms existing methods in dynamic spatial reasoning tasks. |
When Seeing Is not Enough: Revealing the Limits of Active Reasoning in MLLMs (2026.acl-long)
Copied to clipboard
| Challenge: | Existing evaluations of multimodal large language models focus on passive inference, where seeing is not enough. |
| Approach: | They propose a benchmark to evaluate active reasoning in multimodal large language models . they propose to acquire missing evidence and iteratively refine decisions under incomplete information . |
| Outcome: | The proposed model performs better on active reasoning than on passive inference settings. |
