I don't understand how this can be used from scikit-learn? It seems to me like this feature isn't finished. Can you do an example that compares SVDD to standard one class SVM, please. |

Support Vector Data Description (SVDD) could be a nice enhancement to OneClassSVM implementation.
A technical implementation is described in this paper:
http://www.csie.ntu.edu.tw/~cjlin/papers/svdd.pdf
Source code compatible with libsvm is available here:
http://www.csie.ntu.edu.tw/~cjlin/libsvmtools/#libsvm_for_svdd_and_finding_the_smallest_sphere_containing_all_data
I have modified the sklearn/svm/src/libsvm/svm.h and svm.cpp files to add additional functionality of SVM.
