自进化智能体（Agent）又迎新进展。 近日，Meta 超级智能实验室与伊利诺伊大学厄巴纳-香槟分校（UIUC）联合提出了Dr. Zero 框架，使 Agent 能在零训练数据条件下实现高效自我进化。 据介绍，该框架解决了多轮搜索 Agent 在无数据自我进化中面临的"问题多样性受限"、"多步推理与工具使用仍需大量计算资源"等难题。 研究团队创新性地提出了"跳步分组相对策略优化"（HRPO）方法，通过聚类结构相似的问题来构建鲁棒的群组级基准，在保证训练有效性的同时，避免 了自我进化过程中昂贵的嵌套采样需求。 实验显示，该框架在复杂问答任务中，无需人工标注数据，性能即超越全监督基线高达 14.1%，证明了搜索增强模型在高级推理任务中的强大潜力。 同时，在没有任何人类标注数据的情况下，通过合理的架构设计与奖励机制，智能体完全能够自发涌现出复杂的推理与搜索能力。这为未来解决数据稀缺 环境下的模型训练问题提供了新的思路。 AI自我进化的数据稀缺难题 训练一个强大的模型，通常需要海量且高质量的人工标注数据。尤其是在涉及复杂推理、多步搜索的任务中，获取精准的标注数据不仅耗时，而且成本极 其高昂。虽然"自适应语言智能体"的 ...

Group 1 - Bank of America upgraded its rating on nuclear startup Oklo (OKLO.US) from "neutral" to "buy," raising the target price from $111 to $127 due to a binding agreement with Meta (META.US) to co-develop a phased 1.2 GW advanced nuclear power plant [1] - The agreement includes customer prepayments to fund early development before the final power purchase agreement (PPA) is signed, providing tangible evidence of execution and commitment from partners [1] - Analysts believe that investors are increasingly seeking concrete evidence of advanced nuclear moving from concept to execution, and the agreement with Meta provides such proof [1] Group 2 - Recent news regarding data center operator Switch's new geothermal supply has somewhat overshadowed the positive factors for Oklo [2] - The geothermal PPA is relatively small and aligns with Switch's multi-technology strategy, serving as incremental support rather than replacing Oklo's potential 12 GW project under the memorandum of understanding (MoU) with Switch [2] - The analyst noted that Switch's significant share in the announced approximately 14 GW project pipeline indicates that the geothermal supply is a minor addition compared to the larger load demands of hundreds of megawatts to several gigawatts [2]
