probability density estimation by using libsvm #149

Open hp-ekko opened 5 years ago

hp-ekko commented 5 years ago

I did not find instructions on how to use libsvm for probability density estimation. Can you provide relevant help, thank you

We don't have prob density estimation.. For unsupervised data, all we have is one-class SVM. For supervised data, we do have prob outputs, but I guess they are not what you want.

Thank you for your reply. If I want to use it for probability density estimation, do I need to modify this library, for example, modify svm.cpp.

Yes you need to modify svm.cpp (and even need to develop the methodology)
