Beginner: Tree to rule

cristiano

Hi!
I'm a new user of RapidMiner and I'd like some help for exporting the Tree model rules in some formats.

I think "Tree to rule" is a good solution, but I dont know how to link it to my model and if it's the right solution....

Any suggestions would be really appreciated.

Thanks again

C.

Hi cristiano,

you can export the model into xml which can further process:

<?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="296" width="547">
      <operator activated="true" class="retrieve" compatibility="5.0.8" expanded="true" height="60" name="Retrieve" width="90" x="45" y="75">
        <parameter key="repository_entry" value="//Samples/data/Iris"/>
      </operator>
      <operator activated="true" class="multiply" compatibility="5.0.8" expanded="true" height="76" name="Multiply" width="90" x="179" y="75"/>
      <operator activated="true" class="tree_to_rules" compatibility="5.0.8" expanded="true" height="76" name="Tree to Rules" width="90" x="313" y="75">
        <process expanded="true" height="510" width="847">
          <operator activated="true" class="decision_tree" compatibility="5.0.8" expanded="true" height="76" name="Decision Tree" width="90" x="313" y="30"/>
          <connect from_port="training set" to_op="Decision Tree" to_port="training set"/>
          <connect from_op="Decision Tree" from_port="model" to_port="model"/>
          <portSpacing port="source_training set" spacing="0"/>
          <portSpacing port="sink_model" spacing="0"/>
        </process>
      </operator>
      <operator activated="true" class="write_model" compatibility="5.0.8" expanded="true" height="60" name="Write Model" width="90" x="447" y="75">
        <parameter key="model_file" value="tree_model.xml"/>
        <parameter key="output_type" value="XML"/>
      </operator>
      <connect from_op="Retrieve" from_port="output" to_op="Multiply" to_port="input"/>
      <connect from_op="Multiply" from_port="output 1" to_op="Tree to Rules" to_port="training set"/>
      <connect from_op="Tree to Rules" from_port="model" to_op="Write Model" to_port="input"/>
