This means that we would make one binary variable for each of the 10 most frequent labels only, this is equivalent to grouping all other labels under a new category, which in this case will be dropped. Thus, the 10 new dummy variables indicate ...

Web毫无疑问，这是一个糟糕的方案。 该模型的预测会有大量误差。 我们使用one hot编码器对类别进行“二进制化”操作，然后将其作为模型训练的特征，原因正在于此。 当然，如果我们在设计网络的时候考虑到这点，对标签编码的类别值进行特别处理，那就没问题。 不过，在大多数情况下，使用one hot编码是一个更简单直接的方案。 另外，如果原本的标签编码是有 …
