how to convert non nominal to nominal?

    Hello @vikki499

    Is your non-nominal data "text" or "numerical"? There are operators that change text to nominal, numerical to polynomial. So you can select based on your type of data.

    Thanks,

    If your attribute is text, perhaps there is a good reason why it is not nominal, e.g. it may have several thousand possible values. If this is so, I'd first parse the text (e.g. with Process Documents) and create a large collection of term-attributes. If at the end you decide you have too many, you could weight them against the label and select top k based on these weights.
