UCI Repository - how to load data
  • Welcome,

    How can I prepare data, I have something like this http://archive.ics.uci.edu/ml/machine-learning-databases/breast-cancer-wisconsin/. I need to add labels and remove commas. Which tool shoud I use ?
  • Hello,

    I use a combination of Excel and notepad++ (or some other text editor) to manipulate small datasets but in this case you don't need to worry about that because that dataset is part of the sample runs that ship with GeneXproTools (the Breast Cancer classification sample).

  • Thank you,

    one more, what shoud I do with records contain '?' values ?
  • Hello,

    Records containing ? are missing records and GeneXproTools automatically replaces them with zero (in this case) so you don't have to do anything. Later, and if you want, you can change them to a different value you deem more appropriate by choosing the menu Data->Missing Values Mapping, selecting the variable with the missing values and changing the mapping as in the attached image.
  • thank you

Howdy, Stranger!
