No operator description 'W-MultilayerPerceptron'
laurab
Hi,
I am having trouble trying to use 'W-MultilayerPerceptron' in java. I am initilaising rapidminer:
System.setProperty("rapidminer.home", "file:///C:/Rapid-I/RapidMiner-4.3");
RapidMiner.init();
And rapidMiner.jar and weka.jar are both on the build path. I am trying to create the opertor as follows:
Operator model = OperatorService.createOperator("W-MultilayerPerceptron");
model.setParameter("L", "0.3"); //learning rate
But I always get the following error:
com.rapidminer.operator.OperatorCreationException: No operator description object given for 'W-MultilayerPerceptron'.
I really cant see what i am doing wrong?
Thanks Laura

Hi Laura,
does this error occur if you use rapid miner operators?

Hi Sebastian,
Thanks for getting back to me. I have fixed the error now thouhg. I was not setting Rapidminer.home correctly.
I was setting:
"file:///C:/Rapid-I/RapidMiner-4.3"
but have changed it :
"C:/Rapid-I/RapidMiner-4.3"
and this works fine now.
Thanks alot
Laura
