Hello,
How to call the "MultilayerPerceptron" operator from java: Exception in thread "main" com.rapidminer.tools.XMLException: Unknown operator class: 'MultilayerPerceptron'
We didn't find the operator in de API documentation.
Thanks a lot,
Marcel
Answer by Ingo Mierswa:
Hello Marcel,
try
Operator operator = OperatorService.createOperator("W-MultilayerPerceptron");
Works for me at least for version 4.1 of RapidMiner. The "W-" indicates that the operator is originally derived from the Weka library. Of course you have to add the file weka.jar also to your classpath.
Cheers,
Ingo
