Dear Scikit-learn team, First, you guys have built an amazing set of ML tools. I am constantly impressed by your feedback to the mailing list. I wonder if sklearn has a PGM in the works? I've been trying to understand how to code one up, do you have any suggestions where I could look for a python

For the 1.0 release, I would concentrate on machine learning classics, essentially supervised and unsupervised learning methods (i.e. the methods for which our API is robust and well-tested).
