The answer is either a crisp yes (if you are one of those), or a fuzzy probably-not. As Carlos pointed out in Graphical Models class today, if you are a bayesianist then you would attribute a probability in (0,1) to you being a bayesianist.
On another note, I'm finishing up yet another excruciating Probabilistic Graphical Models homework. This time, we had to implement variable elimination for exact inference in bayesian networks. Additionally, we implemented the min-fill heuristic to find a good variable elimination ordering. The 37 node alarm network is depicted above (graphviz baby!). I wonder if my variable elimination code is good enough to work on 1000 node networks. Only one way to find out. :-)
On another note, I've been practicing Milonga del Angel by Astor Piazzolla on my classical guitar.
