[SciPy-user] is there any plan to import BNT(bayesian network toolkit) from matlab?

I believe he's referring to "Pattern Recognition and Machine  
Learning", which was published in 2006. It's quickly become a  
favourite in many circles, and it contains one of the most  
comprehensive treatments of graphical models that I know of in any  
textbook.  The website for the book: http://research.microsoft.com/ 

Conveniently enough for all interested, the graphical models chapter  
is available as a free sample chapter!


Stefan, I think that Bishop's chapters on graphical models, Markov  
Chain Monte Carlo, and variational methods are an excellent place to  

Off the top of my head, these papers are rather illuminating as well:


Once I'm done my coursework for the term and have more time on my  
hands I'll be contributing whatever I can to the effort.
