Papers with PRMBench
R-PRM: Reasoning-Driven Process Reward Modeling (2025.emnlp-main)
Copied to clipboard
| Challenge: | Existing Process Reward Models (PRMs) output evaluation scores directly, limiting both learning efficiency and evaluation accuracy. |
| Approach: | They propose a Reasoning-Driven Process Reward Modeling (R-PRM) which activates inherent reasoning to enhance process-level evaluation. |
| Outcome: | The proposed model outperforms baseline models on ProcessBench and PRMBench by 13.9 and 8.5 F1 scores. |
Error Typing for Smarter Rewards: Improving Process Reward Models with Error-Aware Hierarchical Supervision (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Large Language Models (LLMs) are prone to hallucination, especially during multihop tasks. |
| Approach: | They propose a hierarchical, erroraware discriminative PRM that classifies math errors at each step and combines finegrained signals to estimate step correctness. |
| Outcome: | The proposed model outperforms the prior best in a new stateof-theart PRMScore of 67.7 on a 400Ksample dataset . |
PRMBench: A Fine-grained and Challenging Benchmark for Process-Level Reward Models (2025.acl-long)
Copied to clipboard
| Challenge: | Recent large language models (LLMs) have achieved significant performance in complex reasoning tasks such as mathematics and code generation. |
| Approach: | They propose a process-level benchmark specifically designed to assess the fine-grained error detection capabilities of PRMs. |
| Outcome: | The proposed model measures the accuracy, soundness, and sensitivity of 25 models across open-source and closed-source large language models. |
