How to use W-Vote operator

I have an error when I'm trying to start my process:
Error in experiment setup: Inner operator of a Weka ensemble learning operator 'W-Vote' must be another Weka learning scheme.

I've also used only one weka classifier in subprocess, but error is the same.

This is my process, I want to split training data inside vote operator and put them on svms.

Re: How to use W-Vote operator


It is important for this automatically converted Weka operator that only Weka operator are inside. This includes deactivated operators and preprocessing operator as well.

This process below e.g. works.


<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.3.009">
  <operator activated="true" class="process" compatibility="5.3.009" expanded="true" name="Process">
    <process expanded="true">
      <operator activated="true" class="retrieve" compatibility="5.3.009" expanded="true" height="60" name="Retrieve Golf" width="90" x="45" y="30">
        <parameter key="repository_entry" value="//Samples/data/Golf"/>
      <operator activated="true" class="weka:W-Vote" compatibility="5.3.001" expanded="true" height="76" name="W-Vote" width="90" x="246" y="30">

Re: How to use W-Vote operator

Your Paste Bin Link does not work anymore, but I suppose you want to use RapidMiner's built-in Vote operator instead of W-Vote.

Best regards,
