bsfilter 1.4[01]での確率異常? (2004-03-02 15:00 by a39 #8289)

bsfilter 1.38.4.12, 1.39, 1.40, 1.41で比較をしてみました。prob. DBは1.41でbsfilter -uして再構築してみましたが、状況は変わりませんでした。

tagカテゴリ新説など、tokenizerの仕様変更による変化だと思います。

では，bsfilter.1.4x台への移行は，旧いbsfilterのdbをリセット（削除）して，spam/cleanの学習から始める必要があるのですね．

そうしなくても，ある程度のスコアは出せるようなのですが，偏りが激しいというか，極端に確度が落ちるようなのでそのままの移行では，フラストレーションが溜まるかも…とか思ってしまいました．
