Thanks! This looks interesting, but requires tests. I'm marking it as a WIP (work in progress) pending the addition of tests and documentation.

Coverage decreased (-0.03%) when pulling 5dffb62 on sklef:SVDD into c1e5f94 on scikit-learn:master.

In terms of documentation, I assume this should be discussed under Outlier Detection, and be included in plot_outlier_detection_housing.

The class docstring should refer to the Tax and Duin paper.

There are some conflicts with new version. What is the right way to deal with them? Take new version of sklean and modify it or there is more elegant way?

Less maths and more intuition please: why is this useful? Why is it more/differently useful than a standard SVM? What's the intuition behind it.

We also need a figure, generated from the example (don't check the generated figure in the git, use the fact that it is automatically generated by 'make html').

To merge you can either do a 'git merge master' after updating master, and then resolve conflicts manually, or reapply the changes. Given that there are fairly beeffy changes to the core libSVM organization, it might be worth reapplying the changes.
