best results I've gotten out of the perceptron so far for set 2 have been:
# SUMMARY for threshold 5.0:
# Correctly non-spam: 67468 99.88%
# Correctly spam: 112527 94.49%
# False positives: 82 0.12%
# False negatives: 6556 5.51%
# TCR(l=50): 11.175206 SpamRecall: 94.495% SpamPrec: 99.927%
with intermittent cases where it just goes nuts and gives 30% FNs (with
most of the scores zeroed). I can't particularly figure out what needs
to be done with the parameters to work around it, nor am I keen to sit
here trying sets of params in a trial-and-error fashion...
I'm going to go back to using the GA, see if I can get better results out
of that. if anyone wants a try to fix the perceptron problems for set0
and set2, the full logs are on the zone at:

Theo -- I'm pretty sure it's not a GIGO logs problem, since the results for set
1 and set 3 are quite good, and the freqs look good too. actually, I'll upload
the
freqs for set3, they're worth checking out.
