Copied to clipboard
| Challenge: | Existing methods for fact verification do not target the retrieval of precise evidences. |
| Approach: | They propose a DQN-based approach to retrieval of precise evidences . they propose best thresholds for determining the true labels of computed evidences. |
| Outcome: | The proposed method improves accuracy of fact verification by reducing label bias . it can retrieve evidence consisting of the first two sentences, but it can contain unnecessary sentences . |

| Challenge: | Large Reasoning Models (LRMs) are constrained by the overthinking issue. |
| Approach: | They propose a policy optimization framework that reshapes the exploration and exploitation through two core components: self-imitation and self-guidance exploration. |
| Outcome: | The proposed model achieves superior reasoning efficiency without compromising overall accuracy. |
