AdaJudge: Adaptive Multi-Perspective Judging for Reward Modeling (2026.acl-long)
Copied to clipboard
| Challenge: | Existing reward models rely on a static pooling strategy to condense sequences into scalar scores, which is ill-suited for fine-grained discrimination. |
| Approach: | They propose a framework that jointly adapts representation and aggregation to address these limitations by integrating a static inductive bias with a representational mismatch. |
| Outcome: | Experiments on RM-Bench and JudgeBench show that AdaJudge outperforms strong off-the-shelf reward models and traditional pooling baselines. |
