May 1, 2011 at 14:11 comment added Raphael Sure, I just wanted to point out that you can cover some global characteristics using that model. REG can cover some, too, but will fail to model inherently non-regular structures. (thanks, fixed)

May 1, 2011 at 10:06 comment added Artem Kaznatcheev Thanks! I will take a closer look. Can't Hidden MDPs also capture properties like average degree? That seems like something a regular language should be able to capture, or am I confused? (Also, minor point: the Weinberg, Nebel link has a trailing character that kills the link, it is obvious what link you intended, but if you make more edits it might be worth fixing).

Apr 30, 2011 at 10:00 comment added Raphael Well, yea, non-context-free features get lost. But note that properties like (average) node degrees can be captured. For more, see my edit.
Apr 30, 2011 at 7:20 comment added Artem Kaznatcheev this is cool, but doesn't the context-free nature of SCFG force your learner to neglect certain global structure the networks in your training set might have?
