When running the .mod file over the new data set, I have to put the label_id column at Zero (there is no label_id because it is the one I want to forecast, compare with lesson V, step 2).I am using RM 4.4 and I cannot enter zero in that field (it jumps back to 1). Does one of you know how to deal with this problem?Thank you. Martin @ All

I've been terribly busy and haven't had a chance to look at them. If this is a time critical thing, please post your question to the Rapid Miner forums (see the link in my blog roll). You should have an answer in hours. Regards, Tom Hi Martin, yes I did receive your email with files. I’ve been terribly busy and haven’t had a chance to look at them.

I'm still using RM version 4.0 so I don't know if its a bug or not. Martin, I’d need to see your training data files and your prediction set.

In tutorial V you are using new data and run the algorithm over that new data (to generate the trend signal).My version is RM 4.4 and when putting the label-id to zero (because there is no label in that new excel data file) it switches back to 1. Yes, I do use the excel example source operator (if that is the one you used in the tutorial...)Thanks for your quick response. I appreciate this. Martin Tom,

What version of RM are you using? Martin,

Do you have a solution for this? The error I get is this one:Many operators like classification and regression methods or the PerformancEvaluator require the input example sets to have a label or class attribute. If this not the case, applying these operators is pointless. If you read the data using an ExampleSource, you can specify the label attribute by using a 'label' tag in the attribute description fileI also tried not using "create label" at all, but it doesnt work.Thanks!

You can download it at www.rapid-i.com or www.rapidminer.com. The tutorials were modified load into the new version of Rapidminer.I see you are from NJIT, are you a (former) student of Dr. Kudyba?
