Hi,
I'm working on a project using the kernlab library.
For one phase, I want the "decision values" from the SVM prediction, not
the class label. the e1071 library has this function, but I can't find
the equivalent in ksvm.
In general, when an SVM is used for classification, the label of an
unknown test-case is decided by the "sign" of its resulting value as
calculated from the SVM {-,+}
I want the actual values as a proximal representation of the "strength"
of the decision. (Further from the hyperplane indicates more confidence)
Any suggestions?
