Question

在rapidminer中，我有一个多项式属性，有“戏剧”，“喜剧”和“浪漫”值，但有些行是多值的，例如“戏剧，浪漫”，这是一种我可以在分开的行？

我尝试过分割运算符，但它在单独的属性中显示值，但我想在单独的行中显示这些值。

Answer 1

我认为您要做的是首先使用Split运算符获取单独的属性。表格如下：

word_1, word_2, word_3...
Drama, Romance, 
Comedy, Romance

...

之后你可以在word_ \ d +上使用Depivot将它们放在单个示例中。附件是一个显示此过程的过程。

Answer 2

您可以使用 Nominal to Binominal 运算符为每个单独的值创建新列。
