Traverse and operate an ExampleSet

Hi everyone!
I would like to multiply each value of attribute subset (Att2 - Att10) by value of other attribute (Att1), in a multiple exampleset:

For example:

Att1 Att2 Att3 .... Att10
1 2 2 3
2 3 2 1
3 1 2 1
2 2 1 2

will be:

Att1 Att2 Att3 .... Att10
1 2 2 3
2 6 4 2
3 3 6 3
2 4 2 4

I've worked with macros in this way:

Loop Examples -> Loop Attributes -> Set Data

I'm not sure if this is efficient, does anyone has a better solution?
Thanks !!! ; )

Hola Xannix!

You can also do it like this ..

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.0">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="5.0.8" expanded="true" name="Process">
    <process expanded="true" height="414" width="758">
      <operator activated="true" class="generate_data" compatibility="5.0.8" expanded="true" height="60" name="Generate Data" width="90" x="45" y="30"/>
      <operator activated="true" class="generate_products" compatibility="5.0.8" expanded="true" height="76" name="Generate Products" width="90" x="246" y="30">
        <parameter key="first_attribute_name" value="att1"/>
        <parameter key="second_attribute_name" value="att5|att4|att3|att2"/>
      </operator>
      <connect from_op="Generate Data" from_port="output" to_op="Generate Products" to_port="example set input"/>
      <connect from_op="Generate Products" from_port="example set output" to_port="result 1"/>
      <portSpacing port="source_input 1" spacing="0"/>
      <portSpacing port="sink_result 1" spacing="0"/>
      <portSpacing port="sink_result 2" spacing="0"/>
    </process>
  </operator>
</process>

You'll need to tidy up the attribute names etc., but you get the idea.

Good weekend

Que bueno!
That's good for multiply like my example, but if it's more complicated funtion, Is it correct my way?

Thanks a lot Haddock : )

Hola,

Is it correct my way?

Good questions always have fuzzy answers

On the one hand you correctly adjust the correct numbers, actually only the positive ones I think, on the other hand you need to be aware that you are altering the underlying data, and not just providing a formula evaluation upon it as when you apply an operator. That means of course that the original data gets consumed, so although you can alter the data you can't show that you have, unless of course you make a copy, and not just a memory copy, as the following shows.
