how to initializing valueseries plugin

Hi,

you can get more information about the initialization of RapidMiner together with the plugins in the following thread:

http://rapid-i.com/rapidforum/index.php/topic,26.0.html

Hope that helps,

Hi..

I have to write a Java-Application where i want to make RapidMiner GUI for Classifying Audio Data, I use rapidminer.jar (version 4.0) and rapidminer-valueseries-4.0.jar. First step i make process for process automatic feature extraction audio.

but I got the error-message below :

Plugin is succes loading but there is a message error Exception in thread "main" java.lang.RuntimeException: Illegal operator index in getOperator() (ValueSeriesGP): 0,.
Could anyone plz let me the solution or where i could be going wrong?

Thanks and Regards.

Hello dhanie

Although I do not know much about the value series plugin...

P Jul 27, 2008 1:32:40 PM: [Error] P Jul 27, 2008 1:32:40 PM: [Error] ValueSeriesGP: ValueSeriesGP: Operator has 0 children, should be 1 P Jul 27, 2008 1:32:40 PM: [Error] XValidation: XValidation: Operator has 0 children, should be 2 P Jul 27, 2008 1:32:40 PM: [Error] Process setup not ok P Jul 27, 2008 1:32:40 PM: [Error] There were 2 errors.

I suggest to create a valid setup and try it again. Maybe the description of the ValueSeriesGP-Operator is helpful.

greetings

Steffen

Hi,

Steffen is right. The ValueSeriesGP operator needs an inner operator delivering a performance vector (this information can be checked in the operator info dialog available from the context menu of the ValueSeriesGP operatoror by pressing F1 after selecting it).

If you use a cross validation, it again has to have specified children. I would recommend to perform the online tutorial available from the help menu in order to get the basic ideas between the process setups and you should also have a loop into the examples delivered together with the value series plugin (available from the SourceForge download page).

Cheers,
Ingo

Hello..

Thanks for the answer, actually i tried to make process for Classifying Audio Data. This is the code for the first step is automatic feature extraction. This code will produced operator for the next step feature extraction in xml file, but still error in the error setup, ValueSeriesGP still can't read the children.. Please help me??
