In fact, using this encoding and allowing the model to assume a natural ordering between categories may result in poor performance or unexpected results (predictions halfway between categories). In this case, a one-hot encoding can be applied to the integer representation. This is where the inte...

简介:在Python中,独热编码(One-Hot Encoding) 在Python中,独热编码(One-Hot Encoding)是一种将分类变量转换为数值型数据的常用方法,它通过创建一个二进制向量来表示类别特征,其中只有一个维度是1(对应当前类别的指示器),其余所有维度都是0。这种编码方式有利于机器学习算法处理分类特征,因为许多算法需要输入数值形式...
