Zusammenfassung:Discriminative learning models such as Logistic Regression (LR) has shown good performance in spam filtering tasks. While most previous researches on LR have used binary features, this discards much useful information. To overcome this problem, information theory based feature valuing method for LR instead of traditional binary features is presented. The effectiveness of our approach has been evaluated on TREC, CEAS, and SEWM test sets. Results show that the proposed method outperforms the traditional binary features in the most test sets.
