监督学习未死,一题训练五小时起飞!华人学者新方法20倍训练效率释放大模型推理能力
量子位· 2025-08-04 07:00
Core Viewpoint - The article discusses the breakthrough of One-Shot Critique Fine-Tuning (One-Shot CFT) in enhancing reasoning capabilities of large language models (LLMs) with minimal data and computational resources, outperforming traditional reinforcement learning (RL) methods and small-scale supervised fine-tuning (SFT) approaches [1][3][14]. Group 1: One-Shot CFT Methodology - One-Shot CFT is a new method that allows models to learn reasoning by analyzing the quality of answers rather than merely imitating them, thus providing a deeper learning signal [3][12]. - The process involves selecting a representative task, generating multiple answers using various models, and then having a more powerful model critique these answers, which serves as the supervision signal for training [4][5]. - The entire training process requires only one question, multiple answers, and critiques, taking approximately 5 GPU hours, significantly less than RL methods [5][14]. Group 2: Performance and Results - In experiments, Qwen2.5-Math-7B achieved a 15% accuracy increase after One-Shot CFT fine-tuning on a single question, surpassing both RL and full supervised fine-tuning models that used tens of thousands of training samples [9][10]. - The method demonstrated strong performance across various mathematical and logical reasoning tasks, with accuracy improvements ranging from 10% to 16% in specific sub-tasks [10][11]. - One-Shot CFT showed stability and reproducibility across different tasks and model configurations, indicating its robustness [11][13]. Group 3: Advantages of One-Shot CFT - The method emphasizes critical learning, allowing models to understand why answers are correct or incorrect, which enhances the depth of learning compared to traditional SFT [12]. - It introduces multi-perspective inputs by generating multiple answers and critiques for a single task, closely mimicking human learning processes [12]. - The training signals from critiques are highly generalizable, reducing the risk of overfitting and allowing for easier transfer to new tasks [12]. Group 4: Accessibility and Practical Implications - One-Shot CFT's low computational cost makes it accessible for individual researchers, resource-limited labs, and startups, providing a cost-effective solution for enhancing reasoning capabilities [14][15]. - The entire process is open-source, including training scripts, model parameters, and datasets, which significantly lowers the barrier for replication and experimentation [17].

Sou Hu Cai Jing· 2025-05-06 04:01
5月港股以"科技领涨+全市场普涨"的强劲姿态迎来开门红,$港股科技50ETF(SZ159750)$今天盘中一度涨至2.8%,临近午间收盘成交额突破1亿,换手率超 18%,两融品种交投十分活跃。 从K线来看,恒生科技5月2日大阳线正好触及关税大跌缺口上沿,包括今日的震荡,表明在此处依然承压。 港股科技指数更强一些,2号大涨已经突破了大跌缺口上沿,今天盘中的下探也回踩了这一位置。 港股行情本质是"钱潮"驱动的估值修复行情。 可以看到两只指数午盘已经双双翻红,这个位置有阻力,但势头很猛,率先突破的港股科技指数后续弹性可能更大。 4月南向大幅涌入港股将近2000亿,今年已超6000亿元,差不多是去年同期的三倍,市场预计全年仍将突破万亿元。这说明内地资金很清楚:港股科技现在 还趴在估值洼地里。恒生科技市净率在近十年18%左右的历史分位,相当于过去十年里只有10%的时间比现在便宜。 不止南向,外资买港股买得也很猛,把港元都买贵了。今天上午,香港金管局在市场卖出605.43亿港元,因为港元汇价触及强方兑换保证。这是自2020年10 月28日以来,港元首次触发联系汇率机制下的强方兑换保证。 金管局表示,近期港元偏强主要由于股 ...
智通决策参考︱5月行情值得期待
Sou Hu Cai Jing· 2025-05-06 00:53
【主编观市】 四月最后一天恒指往上,给五月行情带来指引。 一般放长假海外市场上涨的概率偏大,美股有几个催化: 1,海外AI巨头数据超预期,假期内大涨。如微软、mate等。 2,美国4月非农数据超预期。新增17.7万,大幅超出预估的13.8万增量。 3,特朗普做预期管理,不断释放各种签署协议的所谓利好。 优必选(09880) 2024 年公司实现营收 13.05 亿元,同比+23.7%;毛利润 3.74 亿元,同比+12.4%。主要得益于教育智能 机器人和定制智能机器人产品收入增长。 但这依然只能作为短期来看,看下伯克希尔的现金储备从2024年底的约3340亿美元上升至创纪录的3477 亿美元,显示巴菲特仍在等待合适的投资机会。 当地时间5月7日,美联储将公布最新利率决议。目前市场一致预期,美联储将按兵不动。 对国内而言,汇率走强才是关键,5月5日,离岸人民币盘中一度升穿7.20关口,为去年11月以来首次, 创近半年以来新高。亚洲其它货币也延续上周五的涨势,集体向上脉冲,这意味着美国经济衰退概率上 升、未来利率可能走低。市场普遍预期美元可能续贬值。 财政部今年赤字率按4%安排,比去年提高1个百分点,赤字规模达到 ...
