The part I am most enthusiastic about is fixing the CV generators, though
this could be a merge nightmare since we are in the process of changing the
API. We need it to figure out which modifications are most likely to get in
first.
Lars did some work on semi-supervised naive bayes. Since this is a
classical algorithm, this would be a good candidate. Lars, if you read
this, could you give a link to the latest version of your work?
Thanks,
M.
