    Hi Shashwat,

    "8" is a number, "Single" is not a number.

    You can't use the Parse Number operator on this kind of data.

    Hi Shashwat,

    If you need numeric values you can i.e. use the "Nominal to Numerical" operator.

    Can you show me or can you elaborate the same ?

    Hi Shashwat,

    The Nominal to Numerical operator allows you to encode Nominal values, like your "Married, Single, Together, Divorced, Widow" values into either Unique Integers like "0,1,2,3,4" or into a dummy encoding, which means new attributes with either 0 or 1 for each of the possible Nominal values.


    Here is an example processes that applies both methods onto your csv file:

    <?xml version="1.0" encoding="UTF-8"?><process version="10.3.001">

    It is in XML format kindly provide the right format

    Hi Shashwat,

    you can copy and paste the xml into the Process panel of RapidMiner Studio.

    This will replace your current process with the one from the XML, so please save your work first and start a new blank process first.

    Hi Shashwat, you will need to paste Jonas' XML text  into a program like Notepad, and then save it as a filename.rmp file, then you can import it into AI Studio.  These Community posts will not attach an rmp file, which is probably why Jonas did not send it to you.  Here, I am attaching a file containing Jonas' XML, named Jonas.xml.txt, which I can do because this post allows attachments of text files.  You can download Jonas.rmp.txt, rename it to Jonas.rmp and the import it into AI Studio.
