Re: [9fans] spam filtering fs

[steve.simon@snellwilcox.com]

The problem with the "upas/spam -y <spammail" approach is that the
word frequency tables need to be kept up to date for the best results,
and making the user type this in is unlikely to do this.

If you forget to add a new strain of spam or valid emails to the tables they
will not continue to learn and thus the threshold of spamminess used will
drift from the optimum - you will start to lose valid emails or get more spam.

An important feature of a user interface for baieien spam classifiers is
the equal ease with which the user can submit spam and valid emails to
the training code, otherwise the whole system becomes biased in favour
of least effort for the user :-)
