"support vector machine"

jeje

Hi, I ran SVM with kernel type set to polynomial on RM and it used to work fine. But after more experiments It started to  giving errors Cannot deliver AttributeWeights with parameter "kernel_type" set to "polynomial".  May I know what I did wrong? After a few weeks,  I reinstall RM and now Even the field changes , It used to be kernel shift =1, max evaluations= 500 , generations without improvement =10, population size =10, inertia weight =1.0 and global best weight =1.0  but now it changed to convergence epsilon= 0.001, max iterations = 100000, L pos = 1.0 etc. I am almost certain that I didn't use SVM (PSO)
Thanks in advance

Hey,

to be honest I have never used an SVM besides the standard SVM and the libSVM with linear and rbf kernel, and once in a while the one-class svm. These implementations and kernels should be sufficient for all real-world applications and work reliably.

Best, Marius

Even when I used the standard SVM , decision tree or k NN with cross validation , the output shows no confusion matrix (accuracy), precision, recall, and AUCs and it used to be there.

Ok, can you please post your process setup?

jeje

Do you mean process setup as in the main process? There used to be no error "Decision Tree cannot handle numerical label." but now it has. and the same for all other models.

Hi jeje,

I think Marius ment your process setup as XML as it is described here: http://rapid-i.com/rapidforum/index.php/topic,4782.0.html
But I have another question: How did you manage to place your operators outside the process panel?

Best,
Nils

It always appear like that everytime i drag the operators .This is the xml code
