Hello Thomas,
Your tutorials are really wonderful. I tried using them and they were really helpful.
I have a small problem at the moment for which I am seeking solution. Any help would be appreciated.
1) Which would be the best algorithm/operator in rapid miner that could help predict 5 outputs from a set of inputs.
I have tried using neural nets but id doesnt give me an accuracy as expected. Now I am playing with evolutionary algorithms to help select best inputs for my neural network.
2) My inputs are not numbers. They are mainly character data type. How can evolutionary algorithm be used to weigh these type of inputs based on a status attribute (which unlike the gold status in your example has 5 values namely active, terminated, withdraw, pause, dropout)
Regards

@Hamid: I’m not sure what you’re doing without seeing your datafile and process. I suggest you visit the Rapid-I forums, they might already have a solution for you.

Hi. I have a question about SVM in rapid miner. I dont know why svm couldn’t create accuracy matrix as k-nn. it just shows root mean square error. what should I do?
I’m working on Text categorization and I have 3 columns. Title,Body and label. Body and title are text and label is numeric.
I used:
read database->process document->select attribute->set role(set label column as label)-> x-validation
