通过 rapidminer 在单独的行中显示多值多项式值

Display multivalued polynominal values in separate rows by rapidminer

在 rapidminer 中,我有一个具有“戏剧”、"Comedy" 和“浪漫”值的多项式属性,但有些行是多值的,例如“戏剧,浪漫”,这是我可以在单独的行中显示这些值?

我试过拆分运算符,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。

您可以使用二项式 运算符为每个单独的值创建新列。

最佳,

大卫

我想你要做的是首先使用 Split 运算符获取单独的属性。 table 就像:

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

..

之后您可以在 word_\d+ 上使用 Depivot 将它们放入单独的示例中。附件是显示此过程的过程。

最好的, 马丁
