神译局是36氪旗下编译团队,关注科技、商业、职场、生活等领域,重点介绍国外的新技 术、新观点、新风向。 编者按:说到底,人工智能最终是能执行、但不能感觉的代码。本文来自编译,希望对您有所启发。 划重点: 此外,人工智能缺乏认知科学家所称的"意向性"。人类思想是对刺激的反应,受情感背景、记忆和主观 经验塑造。人工智能无法复制这一点。它们可能在特定情境下产生与人类相似的输出,但其底层机制仍 是一个缺乏经验的机械黑箱(Searle, 1980;Whitmer, 1983)。 3. 学习而不理解 机器学习,尤其是大型语言模型和深度学习系统,在从数据中学习方面取得了显著进展。这些系统通过 在海量数据集中检测统计模式来学习。然而,在此背景下,"知道"不应与"理解"画等号。一个理解单词 含义的孩子会将其与经验、情感和文化洞察力网络相联系,而人工智能则只会计算词序列的概率。 这一根本区别导致了人工智能中的"脆弱性"。人类能够在不同领域中泛化知识,而人工智能模型在面对 新颖、模糊或对抗性情境时往往难以应对。它们在有限的参数范围内运行,缺乏人类天生的语境意识或 常识推理(Marshall, 1980)。 人工智能可以模拟思维,但 ...

韩国国立首尔大学前校长撰文:我们对中国到底了解多少?
Huan Qiu Wang Zi Xun· 2025-06-27 22:57
在被视为未来经济主导领域的人工智能方面,中国已取得多项成功。过去十年间,全球70%的生成式人 工智能相关专利来自中国,据报道全球47%的顶尖人工智能人才源自中国。 在韩国,我们有许多研究美国和日本的专家,但深入研究中国的却少得多——考虑到中国对韩国未来的 重要性,这一现象令人惊讶。当然,理解任何国家都非易事,尤其是中国这样幅员辽阔、情况复杂的国 家。然而,分析中国科技崛起的成因及影响,是韩国为未来做准备的关键。毕竟,中韩两国注定要在高 端制造业领域展开全球竞争。 来源:环球时报 韩国《中央日报》6月27日文章,原题:我们对中国到底了解多少? 全球范围内,对中国科技能力的认 知正在经历根本性转变,越来越多人意识到中国已崛起为世界级技术和工业产品的生产国。这一认知转 变的主要触发点是近期的"深度求索(DeepSeek)震撼"。尽管受美国出口管制影响无法获取尖端半导 体,这家中国小型人工智能研究公司仍成功开发出可与OpenAI等科技巨头媲美的大型语言模型。 这一成功并非孤例。甚至在DeepSeek取得突破前,已有大量证据显示中国科技水平已达全球领先标 准。例如在无人机领域,中国企业大疆占据全球70%以上市场份额;中 ...
