Hi,

check out this:
http://pages.cs.wisc.edu/~ghost/

GhostView is not strictly needed. It is just there to show the step
workflow on the screen. You can use any other program to display it by
changing the lines 164-174 (there actually already seems to be a
backoff to "display").

Hi Liangyou

I looked into this a bit, and I think that ToSparse() should indeed be
fixed along the lines you suggest. This would mean that hypergraph mira
is currently broken for sparse features, although I don't think kbmira
is affected.

I'm quite busy at the moment, but I'll do some more testing and check in
a fix as soon as I can - in the next week or two,

cheers - Barry
