UnpredictaBench: A Benchmark for Evaluating Distributional Randomness in LLMs

Amirhossein Abaskohi, Amirhossein Dabiriaghdam, Liang Luo +4

We introduce UnpredictaBench, an evaluation that tests the ability of large language models (LLMs) to capture true underlying distributions. As LLMs are increasingly used as substi…

CoLD: Counterfactually-Guided Length Debiasing for Process Reward Models in Mathematical Reasoning

Congmin Zheng, Jiachen Zhu, Jianghao Lin +6

Process Reward Models (PRMs) play a central role in evaluating and guiding multi-step reasoning in large language models (LLMs), especially for mathematical problem solving. Howeve…

Improve Mathematical Reasoning in Language Models by Automated Process Supervision

Liangchen Luo, Yinxiao Liu, Rosanne Liu +9

Complex multi-step reasoning tasks, such as solving mathematical problems or generating code, remain a significant hurdle for even the most advanced large language models (LLMs). V…

Multi-step Problem Solving Through a Verifier: An Empirical Analysis on Model-induced Process Supervision

Zihan Wang, Yunxuan Li, Yuexin Wu +4

Process supervision, using a trained verifier to evaluate the intermediate steps generated by a reasoner, has demonstrated significant improvements in multi-step problem solving. I…
