Whether the svdd in libsvm can support negative examples?

Whether the svdd or one class svm in libsvm can support negative examples?

The readme file says "For one-class SVM, label is not used and can be any number".

However, the link "#74 " say "Support for negative examples in one-class added".

So, I am really confused. Thank you very much for your patience and I am looking forward for your reply.

For oneclass or svdd, the input is not labelled.. So it doesn't matter if you indicate the training labels as positive or negative

Thank you , but in the svdd paper, svdd is able to support negative examples. And I saw #74 seem added this function. So, in libsvm, one-class-svm is not support for negative examples now?

[cjlin1]

No we don't plan to support this
