in http://plg.uwaterloo.ca/~gvcormac/spamcormack06.pdf and earlier TREC
evaluation papers, Gordon Cormack discusses use of "SA-Unsupervised",
SpamAssassin using a simple auto-learning procedure:
> SA-Unsupervised. SpamAssassin 2.3 (Unsupervised automated feedback.) filter-
train is invoked after every message, but with SpamAssassins output
classification rather than the gold standard; that is, its own judgement is fed
back to itself as if it were the gold standard.
SA-Unsupervised outperforms SA-Standard -- the default auto-learning regime --
quite frequently ;) Given this, I think we should offer an autolearn plugin
which implements SA-Unsupervised autolearning, as an off-by-default option.
