Aiming at flaws presented in the two methods mentioned above , author used teiresias , a kind of pattern discovery algorithm , in spam filtering 针对以上传统方法所存在的问题,本文应用基于teiresias模式发现的算法过滤邮件。
5.
Teiresias finds patterns in spam training mail set and normal e - mail training mail set respectively . mutual information is used to select useful patterns in spam patterns . all selected patterns are used to filter e - mails 该算法同时发现出现于垃圾邮件集与正常邮件集中的大量模式,经互信息方法做特征选择后获得有效的垃圾模式来过滤邮件。
