How to fade out data in the result?

Ina

Hello,

Does anybody know if RapidMiner is able to fade out some of the data in the result? I only need some special words from the outcoming wordlist in the result.
Is there any operator which I can give these special words with? So that there are only these words in the result?

Greetings, Ina

Hi Ina,
if I understood you correctly, you are going to filter the resulting wordlist? If it's only for viewing purposes, you could use a process like this:

<operator name="Root" class="Process" expanded="yes">
    <description text="This process plots the learning curve, i.e. the performance with respect to the number of examples which is used for learning."/>
    <parameter key="logverbosity"	value="warning"/>
    <parameter key="random_seed"	value="2004"/>
    <operator name="TextInput" class="TextInput" expanded="yes">
        <list key="texts">
          <parameter key="graphics"	value="C:\Dokumente und Einstellungen\sland\Eigene Dateien\Yale\Workspace 4.5\sample\data\newsGroupTexts\graphics"/>
          <parameter key="hardware"	value="C:\Dokumente und Einstellungen\sland\Eigene Dateien\Yale\Workspace 4.5\sample\data\newsGroupTexts\hardware"/>
        </list>
        <parameter key="output_word_list"	value="resultWordlist.wordlist"/>
        <list key="namespaces">
        </list>
        <operator name="StringTokenizer" class="StringTokenizer">
        </operator>
    </operator>
    <operator name="CSVExampleSource" class="CSVExampleSource">
        <parameter key="filename"	value="resultWordlist.wordlist"/>
        <parameter key="read_attribute_names"	value="false"/>
        <parameter key="comment_chars"	value="@/&gt;
        <parameter key="use_quotes"	value="false"/>
    </operator>
    <operator name="ExampleFilter" class="ExampleFilter">
        <parameter key="condition_class"	value="attribute_value_filter"/>
        <parameter key="parameter_string"	value="resultWordlist.wordlist (1)=Path|club"/>
    </operator>
</operator>

It first imports the texts and writes the WordList as file. This wordlist is then read in as ExampleSet. You now have all the abilities to filter the wordlist as for normal exampleSets. For example you could use the ExampleFilter in the way described above. It will keep only examples, with the specified attribute matching the given regular expression.
