I would like to suggest the possibility to add a feature for making correlation matrixes (With Heat Maps into it).

 

Thank you!

    Hi Juan,

     

    several correlation matrix operations are available with our Statistics Extension. Their renderer backgrounds the table with heat map like color. (Okay, it are shades of blue...So it's rather a Cold Map ;) )

    Take a look here: https://oldworldcomputing.com/products/statistics-extension-for-rapidminer

     

    A very simple correlation matrix operator is also available in the core itself if you search for correlation.

     

    Greetings,

      Sebastian

    Hi Juan,

     

    Thanks for your note. As Sebastian pointed out, there is actually a Correlation Matrix operator in RapidMiner Studio which can be found in the operator group Modeling -> Correlations. Here is the most basic sample process to use it:

     

    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
    <process version="7.1.001">
      <context>
        <input/>
        <output/>
        <macros/>
      </context>
      <operator activated="true" class="process" compatibility="7.1.001" expanded="true" name="Process">
        <process expanded="true">
          <operator activated="true" class="retrieve" compatibility="7.1.001" expanded="true" height="68" name="Retrieve Iris" width="90" x="45" y="34">
            <parameter key="repository_entry" value="//Samples/data/Iris"/>
          </operator>
          <operator activated="true" class="correlation_matrix" compatibility="7.1.001" expanded="true" height="103" name="Correlation Matrix" width="90" x="179" y="34"/>
          <connect from_op="Retrieve Iris" from_port="output" to_op="Correlation Matrix" to_port="example set"/>
          <connect from_op="Correlation Matrix" from_port="matrix" 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>

     

    Is that what you were looking for? Or what would be missing?

     

    Thanks

    Tobias

    See Correlation Matrix operator; heatmaps in Statistics Extension.

    To avoid misunderstandings: The Statistics Extension contains the Heatmap like visualization.
