OpenAI的AI复现论文新基准，Claude拿了第一名 近年来，AI 正从科研辅助工具蜕变为创新引擎：从 DeepMind 破解蛋白质折叠难题的 AlphaFold，到 GPT 系列模型展现文献综述与数学推理能力，人工智能正逐步突破人类认知边界。 今年 3 月 12 日，Sakana AI 宣布他们推出的 AI Scientist-v2 通过了 ICLR 会议一个研讨会的同行评审过程。这是 AI 科学家写出的首篇通过同行评审的科研论文！ 这一里程碑事件标志着 AI 在科研领域的突破，同时人们也在进一步探索 AI 智能体的自主研究能力。 4 月 3 日，OpenAI 推出了 PaperBench（论文基准测试），这是一个用于评估 AI 智能体自主复现前沿人工智能研究能力的基准测试系统。如果大模型智能体具备了自动写 AI / 机器学习研究论文的能力，既可能加速机器学习领域的发展，同时也需要审慎评估以确保 AI 能力的安全发展。 PaperBench 在多个重要的 AI 安全框架中发挥评估作用： 用于 Anthropic 负责任扩展政策（Responsible Scaling Policy）中的自主能力评估 应用于谷歌 DeepMind 前沿安全框架（Frontier Safety Framework）中的机器学习研发评估 论文标题：PaperBench: Evaluating AI’s Ability to Replicate AI Research 论文链接：https://cdn.openai.com/papers/22265bac-3191-44e5-b057-7aaacd8e90cd/paperbench.pdf 研究团队构建了一个测试环境，用于评估具有自主编程能力的 AI 智能体。在该基准测试中，研究团队要求智能体复现机器学习研究论文中的实验结果。完整的复现流程包括论文理解、代码库开发以及实验执行与调试。这类复现任务具有较高难度，即便对人类专家而言也需要数天时间完成。 测试基准选取了机器学习顶会 ICML 2024 的 20 篇入选论文，还都是 Spotlight 和 Oral 的。这些论文覆盖了 12 个不同的研究主题，包括 deep reinforcement learning、robustness 和 probabilistic methods 等。每篇论文都配备了详细的评分标准，共计 8316 个可独立评估的复现成果。为确保评估质量，PaperBench 中的评分标准均与原论文作者协作制定，并采用层级结构设计，使复现进度可以在更细粒度上进行衡量。 鉴于机器学习论文的复杂性，人类专家评估单次复现尝试往往需要数十小时。为提高评估效率，研究团队开发了基于 LLM 的自动评判系统，并设计了 JudgeEval 辅助评估框架，用于将自动评判结果与人类专家评判的金标数据集进行对比。其中，使用定制框架的 o3-mini-high 评判器表现最佳，在辅助评估中获得 0.83 的 F1 分数，证明其可作为人类评判的可靠替代方案。 研究表明，智能体在复现机器学习研究论文方面展现出了不容忽视的能力。Claude 3.5 Sonnet （最新版）在配备基础代理框架的情况下，于 PaperBench 基准测试中获得了 21.0% 的得分。 研究团队选取了 3 篇论文组成的测试子集进行深入评估，以机器学习博士的表现作为人类基准（采用 3 次测试中的最优成绩）。在 48 小时的测试时间内，人类基准达到了 41.4% 的得分，而 GPT-4（o1）在相同子集上获得了 26.6% 的得分。此外，研究团队还开发了一个轻量级评估版本 ——PaperBench Code-Dev，在该版本中，GPT-4 的表现提升至 43.4% 的得分。 PaperBench
