把视频时长视为同时影响历史曝光和观看时长的混杂因素，通过“按时长等频分组 → 把观看秒数转成组内分位数 → 共享模型预测分位数 → 组内逆 CDF 恢复秒数”，抑制历史系统对长视频的额外偏好，同时保留长视频天然具有更大观看时长上限这一合理效应。 0. 论文信息与阅读范围 项目 内容 标题 Deconfounding Duration Bias in Watch-time Prediction

第一章：广告为什么存在阿强的烦恼阿强是个卖零食的小老板，在城南的集市摆了一个摊。他的货好、价格公道，但每天来逛的人虽然不少，买单的却寥寥无几——大多数人只是路过，根本不知道他在卖什么。 阿强的问题，其实是一个古老的经济学难题：信息不对称。 他有货，市场上有人需要，但双方不知道彼此的存在。这中间缺了一个「连接器」。 广告，就是这个连接器。
