Note, it is very well recognized in the intrusion detection research
community that the DARPA dataset (and even more so the KDD Cup dataset
dervied from it) is useless for assessing detection algorithms.  In some
ways, it's worse than useless because it's an "attractive nuisance", i.e.,
it's tempting to use it because of its ready availability.  So you really
should refrain from trying to base any sort of meaningful research on it.
