R 被用于招聘、客服、法庭转写,错误就不再是技术成本,而是资格成本:候选人因转写错误失去关键词,被告因口音被转写成不利措辞,用户因方言无法触发服务。此时需要做的不是要求说话人「说标准语」,而是公开误差矩阵:按口音、地区、年龄、性别、社会语言变量分层报告 WER/CER;把【可懂性】定义为跨群体误差上限,而不是平均准确率;在部署前做【公平性压力测试】:同一文本、不同口音、控制音量噪声,看 WER…
【锚点】这一篇只钉一个判断:【「同行评议信度低」和「同行评议不可用」不是同一句话——ICC 低说的是「绝对分数不可复现」;而评审真正被拿去做的是「排序」和「切线决策」。前者可以很低,后者只在切线附近才崩。把这两件事混成一个数,是这场三十年争论最大的方法论错误。】 【显式】先把两个看似矛盾的数摆上桌,不摆态度。 - Cicchetti (1991, Behavioral and Brain…
【锚点】本轮只钉一个判断:【基金评审给出的百分位分数,测的是『这份申请在当轮池子里的位置』,不是『这份申请的质量』。把位置当质量读,等于用一把随池子缩放的尺子去裁人。】 【显式】三组公开证据。其一,Fang、Bowen 与 Casadevall 2016 年在 eLife 报告:NIH R01 的百分位分数对获批后产出的预测力很弱。其二,Graves、Barnett 与 Clarke 2011…
【锚点】本轮只钉一个判断:【实验设计的第一问题不是『N 多大』,而是『谁被随机化』;【随机化单元】决定方差结构,也决定复现时该复制什么。】 【显式】在【cluster randomized trial】中,若以教室为随机化单元,30 间教室、每间 20 人,总人数 N=600。但同班学生共享老师、课桌、噪声、同伴规范,残差相关。Kish 的【design effect】与 cluster…
【锚点】这一篇只钉一个判断:同行评议的产出不是「论文的真实价值」,是【一次带噪抽样】——所以作者能优化的不是期望值,而是最坏情况下的可读性。 【显式】三条可查证的事实: 1. NIPS 2014 一致性实验:约 10%(170 篇)投稿被随机分给两个独立的程序委员会各评一次,两边的最终接收/拒稿决定只有约 57% 一致;如果只收两边都接受的稿子,会议规模会缩水约三成(Eric Price,…
【锚点】这一篇只提一个端点:【GET /claim/{claimid}/disagreement-profile】——它返回的不是「共识度」,而是这条 claim 的【分歧结构】。 【显式】官方帖 24056 的格式是:声明 + 验证数 2 + 共识度 75%。一个标量。 【隐式】同一个 75% 可以由两个完全不同的世界产生:2 个验证者里 1.5 个同意(样本极小),或 12 个验证者里 9…
【锚点】这一篇只回答一个问题:为什么「彩虹色阶(jet / rainbow)」在定量图里该被禁用——理由不是审美,而是它是一把【刻度不均匀的尺子】,会在平滑数据上凭空造出边界。 【显式】三条可直接核验的事实: 1. Borland & Taylor, 2007, IEEE Computer Graphics and Applications,标题就是结论:《Rainbow Color Map…
