"Java application not printing output for RapidMiner Process"

anik

I have created one association rule mining process in RapidMiner and calling it from JAVA application.. But, it's not printing any output..But, it's showing "Process finished successfully after 0 s"...

This is what showing in console:

Can anyone please solve this issue? ???
Help is highly appreciated....

Hi,

1) You are running the process twice, the first time you are ignoring the output ports. Doesn't break anything, just wanted to mention it.
2) You have not posted the process XML, so I can only guess. Either you have not connected the last operator to the process output ports (top right corner of the process) or your output is NOT an ExampleSet.

Marco

Hi Sir:

But, I am getting output in RapidMiner..
Actually I am very new in RapidMiner.. First time I am using this..
As developing all the algorithms in time consuming and tough in JAVA.. That's why I am creating process in RM and calling it in JAVA..

I am attaching the XML code below..

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="6.1.000">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="6.1.000" expanded="true" name="Process">
    <process expanded="true">
      <operator activated="true" class="retrieve" compatibility="6.1.000" expanded="true" height="60" name="Retrieve dd" width="90" x="112" y="75">
        <parameter key="repository_entry" value="//NewLocalRepository/dd"/>
      </operator>
      <operator activated="true" class="nominal_to_binominal" compatibility="6.1.000" expanded="true" height="94" name="Nominal to Binominal" width="90" x="246" y="75"/>
      <operator activated="true" class="fp_growth" compatibility="6.1.000" expanded="true" height="76" name="FP-Growth" width="90" x="514" y="75">
        <parameter key="min_support" value="0.8"/>
      </operator>
      <operator activated="true" class="create_association_rules" compatibility="6.1.000" expanded="true" height="76" name="Create Association Rules" width="90" x="648" y="75"/>
      <connect from_op="Retrieve dd" from_port="output" to_op="Nominal to Binominal" to_port="example set input"/>
      <connect from_op="Nominal to Binominal" from_port="example set output" to_op="FP-Growth" to_port="example set"/>
      <connect from_op="FP-Growth" from_port="frequent sets" to_op="Create Association Rules" to_port="item sets"/>
      <connect from_op="Create Association Rules" from_port="rules" 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>

Could you please help me now?

Hi,

you are returning association rules, not an example set. As you can see in your code, only if the returned result matches an ExampleSet something is done.

Have a look at the package "com.rapidminer.gui.viewer". There are various GUI classes which display different IOObjects in RapidMiner Studio. For example, an AssociationRuleTableVieweris in there. Have a look at where the constructors are called for these GUI objects, then you will find the actual IOObject implementations. Then you can cast your IOObject results of your process to the appropriate classes and work with them. By looking at the GUI classes you can get a first impression of what information you can display.

Regards,
Marco

Hi,

You can try the below code to print out the association rules 

   com.rapidminer.Process process = new com.rapidminer.Process(new File("FPGrowth.rmp"));

			IOContainer ioResult = process.run();
			AssociationRules arules = (AssociationRules) ioResult.getElementAt(0);


			for (AssociationRule ar : arules) {

				System.out.println(ar.toString());

			}

     

Cheers
