📝 摘要(中文)
大型语言模型(LLMs)越来越多地被用作研究协作伙伴,进行假设细化、方法规划和技术分析。然而,现有的对齐方法往往无法同时满足准确性、方法论合理性、逻辑一致性和高效性。本文提出CollabSciReM,一个目标条件奖励框架,将会话级奖励分解为对话质量、科学严谨性和结构效率。通过在300篇科学论文上进行的评估,CollabSciReM在多个基准设置中表现优于科学无关奖励基线,显示出显著的创新性和实用性。
🔬 方法详解
问题定义:本文旨在解决大型语言模型在科学对话中的对齐问题,现有方法在准确性和科学严谨性方面存在不足,导致生成的对话缺乏逻辑性和有效性。
核心思路:CollabSciReM通过目标条件奖励框架,将会话级奖励分解为多个维度,确保生成的对话既具科学性又具逻辑性,从而提升模型的整体表现。
技术框架:该方法包括三个主要模块:对话质量评估、科学严谨性评估和结构效率评估。通过对这三个维度的综合考虑,模型能够生成更符合科学标准的对话内容。
关键创新:CollabSciReM的核心创新在于奖励的分解机制,这一机制与传统的科学无关奖励方法相比,能够更好地平衡对话的质量与科学性。
关键设计:在设计中,使用了特定的损失函数来优化每个奖励维度,并通过对300篇科学论文的评估来验证模型的有效性,确保生成的对话在逻辑一致性和科学严谨性方面达到高标准。

📄 摘要(原文)
Large Language Models (LLMs) are increasingly used as research collaborators for hypothesis refinement, methodological planning, and technical analysis across multi-turn interactions. In this setting, a useful assistant must be accurate, methodologically justified, logically consistent, and token-efficient. Current alignment approaches rarely achieve all of these together. Instruction-tuned models gain conversational quality through verbosity, and we show that science-agnostic general collaborative rewards compress responses at the expense of scientific rigor. We propose CollabSciReM, a goal-conditioned reward framework that decomposes the session-level reward into conversational quality, scientific rigor, and structural efficiency. We also introduce SciQuality, a pairwise evaluation of multi-turn research conversations grounded in 300 held-out scientific papers and scored on six dimensions: methodological soundness, justification, logical consistency, factual correctness, novelty, and responsiveness. Fine-tuned on 8.62K synthetic research conversations, CollabSciReM is preferred on SciQuality over a science-agnostic reward baseline trained on the same data for all four Llama and Qwen models, including a 65.3% win rate at matched response length. For the 7B and 8B models, CollabSciReM outperforms the science-agnostic reward baseline on the primary metric in 8 of 10 single- and multi-turn benchmark settings. In a blind study, domain experts rated CollabSciReM significantly higher on novelty than the general-reward variant and reported fewer hallucinated responses than both the general-reward variant and the base model.
