Devashree Rai, Kesari Verma, A. S. Thoke . Classification Algorithm based on MS Apriori for Rare Classes. International Journal of Computer Applications. 48, 22 ( June 2012), 52-56. DOI=10.5120/7516-0599
Most of the data mining algorithm focuses on frequent patterns, few algorithm emphases on rare items, but rare items [1] also have importance, for example, network intrusion detection, where among various normal connections we need to detect the rare malicious connections. Classification of such a non-uniform data set is a challenging issue. Most classifiers perform poorly in such a data set. Realizing the importance of rare class classification, in this paper we propose a classification algorithm (CBMR Algorithm) that is based on association rules mined by MSApriori approach [2] and is capable of classifying rare classes. The performance evaluation of the proposed algorithm has been done for different data sets [3] and in comparison with existing technique like [4], it is found that algorithm has efficient and superior performance for classifying rare cases.
