我们找到3位大学教授,聊了聊越来越严重的AI幻觉
3 6 Ke· 2025-07-15 03:23
最近,网上出现了一个 AI 幻觉引发的闹剧。 7 月 2 日,网上突然出现大量 " DeepSeek 就 AI 模型违规关联向王一博道歉 " 相关内容,最终被发现其 实是 DeepSeek 在对话中虚构了事件甚至引用了一份在中国裁判文书网上完全查不到的判决书。 而这场闹剧,源于 DeepSeek 在与用户对话过程中产生的幻觉。借此,知危编辑部认为有必要探讨一下 AI 大模型们激增的幻觉率了。 前段时间,OpenAI o3 模型刚发布不久,也因为幻觉率 " 不降反升 " 的现象引发了广泛关注。 OpenAI o3 模型会犯很多匪夷所思的错误。比如,捏造从未运行过的代码,在编码设置中使用无效的非 ASCII 破折号,甚至还会假装自己在调用工具。 在 PersonQA 基准测试中,o3 会在 33% 的问答中出现幻觉,几乎是o1( 16% )的 2 倍,o4-mini 的幻 觉率更是高达 48%,远高于此前发布的推理模型。 近期发布的其他深度思考模型也出现了类似的规律,即随着推理能力增强,其幻觉率也反而更高。 艾伦人工智能研究所科学家 Nathan Lambert 曾发文评论 o3 的推理幻觉,表示这一问题的出现是 ...

从小米人车家全生态发布会 透视未来大家居行业格局?
3 6 Ke· 2025-07-15 03:01
生态本质:从"产品控制"到"场景控制"的转移 传统模式下,用户需通过手机APP或语音助手"指挥"单一设备。而小米的"人车家全生态"正试图通过视觉交互、车外交互以及家居自动响应,将控制权移 交场景本身,实现需求与响应的自动联结。 基于此,家居新范式认为,小米"人车家全生态"的核心突破在于构建三层技术闭环,来实现将控制权移交场景本身: 传感层全覆盖:小米通过部署人体传感器(检测移动/静止)、门窗传感器(识别开关状态)、米家蓝牙温湿度计等环境感知终端产品矩阵,能实时精准 采集物理空间状态,大幅提升自动化可靠性。这意味着,智能家居行业将面临传感数据标准化挑战; 执行层响应快:在人车家全生态协同下,用户在车内可通过语音控制家中的灯光、空调、安防设备。甚至基于传感数据,智能设备可形成自动化决策链。 这种智能终端协同响应,也倒逼家居企业从单品研发转向系统集成; 交互层无感化:小米产品借毫米波雷达等生物感知技术预判需求(如空调自适应呼吸/活动状态),结合地理围栏触发预服务(如车辆联动家居模式), 本质是用空间智能取代人工指令,实现人未到,场景已就绪。当用户享受"所想即所得"的服务时,传统家居的交互逻辑也面临重构。 近日,小米 ...

不结婚、不生娃,但每个月得多交几十块钱的"单身税",这样的交换条件你愿意接受吗? 不同收入区间需要缴纳的育儿支援金费用 全民缴费、定向补贴,在不婚不育渐成主流的日本社会,这项新出台的育儿支援金不仅因其合理性备受争议,还因为其变相"压榨"未育人士,而被外界广 泛解读为日本政府为刺激年轻人结婚生娃而量身定制的"单身税"。 争议制度出台背后,是日本愈发严峻的人口问题:全国儿童数量连续44年下降、2024年出生人口自1899年有统计以来首次跌破70万、国家总和生育率跌至 1.15连续3年创下历史最低...... 日本学界预言,按照这个趋势发展下去,在不久的将来人口下滑将不仅仅是国家财政和社会民生问题,而是关乎日本整个国家存亡。 然而,就在这样的节骨眼上,日本民众却对政府的"救国新政"表示不买账了。 素有"东亚测试服"之称的日本,在饱受少子化和人口老龄化困扰三十年后,决定向全社会单身、未育人士开启一场大型服从度测试。 相关新闻推文已经有超过1400万阅读 据多家日媒报道,日本将于明年4月正式推行一项名为"儿童·育儿支援金"的新制度,要求全体缴纳医保的民众按照实际收入情况,每年最高缴纳12000日 元(约为人民币588元 ...

能坚持健身的人,做什么都会成功的。 世界上有这么一群人,利用上班前、午休时或下班后的一小时时间,把胸、肩、背、臀、腿和核心训练安排得明明白白,就连节假日也不放过自己。 训练结束,遵循着"练完不拍,等于白练"的原则,在肌肉充血状态下,对着镜子自拍一张,配上运动手表上的数据,更新一条来自健身房的朋友圈。最后 再去跑步机上,把坡度调为15度,配速为5公里/小时,用30分钟的有氧运动收尾。 健身痕迹和奢侈品一样,都是可以用来炫耀的。只不过,在人格背书的层面上,健身痕迹的说服力可比奢侈品强多了。 这还不是真正的结束。虽然经常累到没有胃口,但他们还是会抓住运动结束后15分钟的"黄金时期"(最多不能超过半小时),逼着自己摄入香蕉、馒头等 快碳食物,让肌糖原的水平快速恢复,再一股脑喝下那杯墙皮味的蛋白粉。一天的健身环节,到这里才算结束。 这样的运动日常,发生在越来越多中国人的生活中。 随着年岁的增长,人们终于意识到,真正的奢侈品,不再是印着大logo的奢侈品包包,而是不发力时也能看出的肱三头肌线条和背部倒三角。 毕竟,要拥有一个限定款的爱马仕包包,你只需要有购买它的经济实力,最多再加点门店刚好有货的运气;而拥有一副令人羡慕的 ...
