could you pleaase attach your AML file? You are most probably using a numerical label for your data but by the SVM in such configuration only a nominal label is supported.
- radone
Of course, here it is.
I post the xml code because i am not able to attach a file. Sorry.

Thank you so much.

please copy the process file directly from RapidMiner's xml view. Then there aren't these nasty - characters inserted by the internet Explorer.
Another hint: please insert your process in a code area here in this forum. You can reach it with the # sign in the buttons above.
Greetings,
Sebastian
Let's see if this time I'll do it right.
Greetings,
Silvana.
why have you inserted this numerical to polynomial operator? It will map all numerical attributes to polynomial values, and hence the SVM cannot be applied at all?
Greetings,
Sebastian
I am doing an example to learn about rapid-i and classification and prediction issues. In this example we try to classify abalone, 3 classes, so we need to wrap the LibSVMLearner in a Binary2MultiClassLearner operator. Sorry, i can help you more.
Greetings,
Silvana.
yes I understood that you need to have the Polynomial by Binomial Classification operator. But before applying the model you again changed all attribute types. Since the model was learned on numerical attributes, it cannot handle the polynomial ones. You have to simply remove this operator like in this process: Does it work this way?
Greetings,
Sebastian
I remove the operator but there is a problem with the performance operator, it needs that label and prediction have the same type so I have to change the label to polynominal because prediction is nominal. But theres is a problem yet when I try to execute the process, it says: The process now is: Greetings,
Silvana.
of course I cannot execute your process, because I don't have the excel file it is referring to, but I guess my process would just run fine.
Each polynominal and binominal attribute is also of the more generic type nominal, which is some sort of super type, or parent of both in the hierarchy of types.
Could you please send me the error it gives, if you execute my process I posted above?
Greetings,
Sebastian

just send me an email to my mail address at rapid-i.com. It's equal to my last name.

I traced down your problem and it consisted of two components: On the one hand the polynomial by binomial classification operator declares the wrong capabilities, this will be corrected with the next update.
But although the error message might be missleading, it would work with the following process, that correctly defines and transformes types (it spares the label when transforrming to numeric): By the way: Usually transforming nominal values to binominal ones before representing by numbers increases the performance.
