摘要:

大型语言模型在各类下游任务中展现出卓越性能,并广泛应用于多种场景。人类标注的偏好数据被用于训练以进一步提升LLMs性能,但这受限于人类能力的上限。因此,自奖励方法被提出,即LLMs通过奖励自身输出来生成训练数据。然而,现有的自奖励范式在数学推理场景中效果不佳,甚至可能导致性能下降。在本研究中,我们提出了针对语言模型的基于过程的自奖励流程,在自奖励范式中引入了长思维推理、逐步LLM作为评判者和逐步偏好优化。通过迭代的基于过程的自奖励,我们的新范式成功提升了LLMs在多个数学推理基准上的性能,展示了自奖励在实现可能超越人类能力的LLM推理方面的巨大潜力。

英文摘要:

Large Language Models have demonstrated outstanding performance across various downstream tasks and have been widely applied in multiple scenarios. Human-annotated preference data is used for training to further improve LLMs' performance, which is constrained by the upper limit of human performance. Therefore, Self-Rewarding method has been proposed, where LLMs generate training data by rewarding their own outputs. However, the existing self-rewarding paradigm is not effective in mathematical reasoning scenarios and may even lead to a decline in performance. In this work, we propose the Process-based Self-Rewarding pipeline for language models, which introduces long-thought reasoning, step-wise LLM-as-a-Judge, and step-wise preference optimization within the self-rewarding paradigm. Our new paradigm successfully enhances the performance of LLMs on multiple mathematical reasoning benchmarks through iterative Process-based Self-Rewarding, demonstrating the immense potential of self-rewarding to achieve LLM reasoning that may surpass human capabilities.
