coviriate shift指的是训练集和测试集之间的features的分布发生改变,比如训练集中大部分是年轻人的特征数据而测试集中大部分是老年人的特征数据,但是输入到输出的潜在的映射关系是不变的,与之形成对比的另一种更加棘手的dataset shift是输入和输出之间的潜在的映射关系发生改变的情况,比如上文所说的垃圾邮件分类器,因为...
可以说是关于covariate shift的论文集,未来随着算法研究越来越深,这部分的影响应该会越来越大 评分☆☆☆ 不错的论文集,但内容概念有点过时。 评分☆☆☆ 不错的论文集,但内容概念有点过时。Dataset Shift in Machine Learning 2024 pdf epub mobi 电子书 分享链接face...
这种形式的数据集转换称为coviriate shift(协变量偏移)。在1.5节中,引入了另一种简单形式的datase shift:prior probability shift(先验概率偏移)。接下来是关于sample selection bias(样本选择偏差)的第1.6节,关于imbalanced data(不平衡数据)的第1.7节和关于domain shift(域转移)的第1.8节。最后,在1.9节中给出了...

Dataset Shift In Machine Learning—imbalance data 在一个或多个类与其他类相比非常罕见的情况下,很可能会出现被称为“数据不平衡(imbalanced data)”的问题。的确,预测罕见事件(例如,贷款违约)通常会出现这类最具挑战性的问题。这种不平衡的数据问题是dataset shift的一个常见原因。
