The naive Bayes(NB) model has been successfully used to tackle spam,and is very accurate.However,there is still room for improvement.We use a train on or near error(TONE) method in online NB to enhance the performance of NB and reduce the number of training emails.We conducted an experiment to determine the performance of the improved algorithm by plotting(1-ROCA)% curves.The results show that the proposed method improves the performance of original NB.

The naive, Bayes （NB） model has been successfully used to tackle spare, and is very accurate. However, there is still room for improwment. We use a train on or near error （TONE） method in online NB to enhance the perfornmnee of NB and reduce the number of training emails. We conducted an experiment to determine the performanee of the improved algorithm by plotting （I-ROCA）% curves. The resuhs show that the proposed method improves the performanee of original NB.
