The Research and Application of Association Rules Algorithm
in Data Mining
Abstract: In this thesis, the classification and the concepts of association rules in data mining are summarized and discussed, and the Apriori algorithm in association rules is described in detail. Since this algorithm has some disadvantages in the application, on the basis of this algorithm, there has been some of the new improving algorithm, such as AprioriTid algorithm and compression-based screening Apriori mining algorithm. This thesis will be compare and assess the three algorithms to explore their advantages and disadvantages, so the purpose of this thesis is reached.
