Association Rule

This chapter recalls some of the essential concepts related to associ- ation rule mining, which will be utilized throughout the book. Some existing research into the improvement of association rule mining techniques is also introduced to clarify the process. The chapter is organized as follows. In Section 2.1, we begin by outlining certain necessary basic concepts. Some measurements of association rules are discussed in Section 2.2. In Section 2.3, we introduce the Apriori algorithm. This algorithm searches large (or frequent) itemsets in databases. Section 2.4 introduces some research into mining association rules. Finally, we summarize this chapter in Section 2.5.
