Reducing feature sets with cross-entropy

[Ken Williams]

Hi,

I talked with a couple of people at YAPC about a couple of the
AI::Categorize algorithms, and one suggestion was to use cross-entropy
measurements to reduce the number of features (words) considered.  I'm
hoping that by now (now that I've got time to do some work) the right
people have subscribed to this list, and can point me either to a good
reference or discuss the ideas themselves.  True?
