ValueError: labels_true必须是1D 这个错误信息通常出现在使用某些机器学习库(如scikit-learn)进行模型评估时。这个错误的原因是labels_true参数(即真实标签)的维度不正确,它应该是1维数组,但实际传入的可能是多维数组。 基础概念 在机器学习中,标签(labels)是用于标识数据样本类别的数值或类别名称。在进行模型评估时,...

crossentropy，它执行相同的计算，除了这一个以one-hot-coded形式接受标签/目标。替换代码中的这一行：

For binary classification, −y˜i must be correct if y˜i is incor- rect for xi, which implies SIGUA is exactly same as label correction. When does not satisfy that symmetric condi- tion, they become different but still conceptually similar. That being said, for multi-class ...
