本质上差不多,在sklearn的应用上label encoder是给目标类别编码的,ordinal encoder是给特征类别编码的 ...
Soft Labels for Ordinal Regression CVPR-2019 Abstract 提出了简单有效的方法约束类别之间的关系(将度量惩罚无缝合并到ground-truth label表示中) 这种encoding使得NN可以自动学习类内和类间的关系,不需要显示修改网络结构 我们的方法将数据标签转换成软概率分布,使其与常见的分类损失函数(如交叉熵)很好的匹配 结果表明...

First, the label to predict (crash injury severity) is decomposed with one-vs-all binary decomposition. Second, a multiple-output classifier or multiple single-output classifiers (chosen from SVM, XGBoost, and MLP) are trained to predict crash injury severity. Third, the predicted probabilities ...
