how to modify the attribute imported from csv

kukuzry

I am new, and use readcsv read data. The data is row-major, that is, the sample is along the col  and attribute is along the row, which is 3*80 matrix
I have another csv representing OUTPUT, which is 1*80

How can I do that in rapidminer to make it trained by neural network?

    <input/>
    <output/>
    <macros/>

      <portSpacing port="sink_result 1" spacing="0"/>
      <portSpacing port="sink_result 2" spacing="0"/>
    </process>
  </operator>
</process>

HI,

you did not tell us anything about the type of your data etc. Using the Transpose operator is a first step. If you have only numerical values in your data table, you can define the target variable by setting its role to "label" with the Set Role operator, then you can use the Neural Net operator to create a neural net model.

Best regards,
Marius
