Support Vector Machine
Hey guys,
the Random Forest works so far, I'm currently also trying the SVM (Support Vector Machine) as a countercheck. I have filled in a special attribute as Category here, but when I insert the operator Set Role, the SVM operator tells me that a special attribute is missing or insufficient capability. Of course I applied Nominal to Numerical, this requirement must be met. But as I just said, I can't get rid of the error message. As a help the SVM operator offers the "Set Role" operator, but now the svm operator shows me the that the capability is not enough
Thanks for the answers

If you are trying to predict more than 2 classes then a regular SVM does not work. You can choose Support Vector Machine (LibSVM) for multiclass classification.
I becam as resolution the operator "classification by regression", it runs now
but the Operator runs in the background without closing^^
hey @varunm1
can u take a look at the screen please. i have 2 classes and the give mir this Information, that i can use it for 2 classes, but i have in my input data 2 classes ^^
Hi @Flixport
Can you post the process and dataset? If you cannot give the dataset, you can send in a message?

Hello
I am working on this process of @Flixport. In the process there are 4 classes of data(multi-class), we are filtering for samples related to two classes only but it's still giving the other two classes with zero samples. Not sure if this is some bug.

After filtering with Economic and Financial samples, it is still taking agriculture and political but with zero samples. This is the reason regular SVM is throwing an error regarding multiple classes.

Thanks
This is actually desired behavior (so you can still see what the possible values are even if they do not occur in the current value - that is sometimes important). There are a couple of ways to force the re-creation of the meta data for the new data, but my personal favorite is to use a Guess Types operator on that column after the filtering. That will fix the value type to binominal and recreate the meta data.
Hope this helps,
Ingo

Hello @IngoRM
Thanks for informing. That worked. @Flixport, please find the working process with regular SVM in the below process, I added guess types operator and selected Label in operator parameters.

Hey all,
ty for the answers. It works but i become a decteded problem in the SVM Operator (see screen)
is that important or can i ignore it?
@Flixport you can ignore that warning.
Sort by:
1 - 3 of
31
If you are trying to predict more than 2 classes then a regular SVM does not work. You can choose Support Vector Machine (LibSVM) for multiclass classification.
This is actually desired behavior (so you can still see what the possible values are even if they do not occur in the current value - that is sometimes important). There are a couple of ways to force the re-creation of the meta data for the new data, but my personal favorite is to use a Guess Types operator on that column after the filtering. That will fix the value type to binominal and recreate the meta data.
Hope this helps,
Ingo

Is your label binary? If you are trying to predict more than 2 classes then a regular SVM does not work. You can choose Support Vector Machine (LibSVM) for multiclass classification. You can see the number of classes in of your dataset by double-clicking the dataset and going to statistics.
