3 6 Ke· 2025-07-01 02:20
想知道自动驾驶汽车或语音助手等尖端人工智能系统如何实现其惊人的准确性吗?秘诀在于高质量的数据标注。这一过程确保数据被精确标记和分类,从而 使机器学习 (ML) 模型发挥最佳性能。无论您是人工智能爱好者、商业领袖还是技术远见者,本指南都将带您了解数据标注所需的一切知识 , 从基础知识 到高级实践。 一 为什么数据标注对于 AI 和 ML 至关重要 想象一下训练一个机器人识别一只猫。如果没有标记数据,机器人看到的只能是像素——一堆毫无意义的杂乱信息。但有了数据标注,这些像素就被赋予了 有意义的标签,例如"耳朵"、"尾巴"或"毛发"。这种结构化的输入使人工智能能够识别模式并做出预测。 关键数据:根据麻省理工学院的数据,80% 的数据科学家将超过 60% 的时间用于准备和注释数据,而不是构建模型。这凸显了 数据标注 作为人工智能基 础的重要性。 二 什么是数据标注 数据标注是指对数据(文本、图像、音频、视频或 3D 点云数据)进行标记的过程,以便机器学习算法能够处理和理解这些数据。为了使 AI 系统能够自主 工作,它们需要大量带标注的数据来进行学习。 它在现实世界的人工智能应用中是如何运作的 在新兴技术和新行业需求的 ...

招商局狮子山人工智能实验室 投稿 量子位 | 公众号 QbitAI 大模型可以不再依赖人类调教,真正"自学成才"啦? 新研究仅通过 RLVR (可验证奖励的强化学习),成功让模型自主进化出 通用的探索、验证与记忆能力 ,让模型学会"自学"! 当前主流的LLM Agent依然高度依赖于提示词工程、复杂的系统编排、甚至静态规则表,这使得它们在面对复杂任务时难以实现真正的智能 行为演化。 而来自招商局狮子山人工智能实验室的研究团队认为,RLVR范式是智能体(Agent)通往更高通用性和自主性的重要突破口。 于是,他们从两个关键层面出发构建了端到端Agent训练pipeline—— L0系统 : 智能体架构层面 提出了结构化智能体框架——NB-Agent,在经典"代码即行动" (Code-as-Action) 架构基础上进行扩展,使智能体能够操作记忆/上下 文,从而获得类人类的记忆存储、信息总结与自我反思能力。 学习范式层面 探索了一个核心问题:是否可以仅通过RLVR范式,引导智能体从零开始,学会如何规划、搜索、验证与记忆,最终解决复杂的多轮推理 任务? L0系统的框架、模型及训练集已 全部开源 ,详细可见文末链接。 ...
