Output rules

changuel

Hello,
I am using RM in java and I am generating associating rules using FPGrowth. My question is how to parse the resulting rules as in the Gui manner, I wan to get for each rule its support, its confidence, its lift....Is it possible to have the rules in a table as in the gui so as to seperate the premises and the conclusions.
Here is the XML file I used :

<operator name="Root" class="Process" expanded="yes">
    <operator name="CSVExampleSource" class="CSVExampleSource">
        <parameter key="filename"	value="...attributes.csv"/>
    </operator>
    <operator name="Nominal2Binominal" class="Nominal2Binominal">
    </operator>
    <operator name="FPGrowth" class="FPGrowth">
        <parameter key="min_support"	value="0.1"/>
    </operator>
    <operator name="AssociationRuleGenerator" class="AssociationRuleGenerator">
        <parameter key="min_confidence"	value="0.7"/>
    </operator>
</operator>

and here is the java code:

RapidMiner.init(false, true, true, true);

		String modelFile = "operator.xml";
		File processFile = new File(modelFile);
		Process process;

		try {
			process = RapidMiner.readProcessFile(processFile);
			IOContainer input = new IOContainer();
			IOContainer output = process.run(input);
.....

With this code, I can see the generated rules in this manner:
[att1= val1] --> [att2= val2] (confidence: 1.000)

And I want to see the values of the support, lift... and not only the confidence.

Thanks in advance.

Hi there,

The following generates data and makes association rules, which are filed and parsed into an example set. You will get log nasties about unattached files, which you can ignore.
