Developing svd from t-idf

A RapidMiner user wants to know the answer to this question: "Hey there. I'm trying to develop an svd from tf-idf, but when I go to the chart, I can't see the labels of the variables, only the numbers from svd. Does anybody know how to get to the labels? Thank you."

    Hi,

    The input data is not available. But I guess you want check out the "pre" ouput node from SVD?

    Thank you for your comment. Unfortunately, this is not the problem. What I am trying to do is to visualize the svd through a splotter plot type, but with the labels of the attributes, not with the coordinates
  • rmtorresrmtorres Member Posts: 4 Contributor I
    Finally, I have got a solution! When reading data from Excel, in Parameters  you have to go to "data set meta information", and in "edit list" you have to select in the first row the attribute as "text" and "label". I have highlighted in black / bold just aboved.
