Numerous studies have dealt with the association rules of a number of data mining techniques. From this point of view, studies identifying frequent patterns using frequent pattern trees are progressing actively. The FP-Growth technique using a frequent pattern tree shows superior performance over the existing well-known "Apriori" technique. However, the FP-Tree has a problem that is to degrade performance because of the considerable FP-Tree size. This problem is solved to previous research, but it has another problem to be inapplicable to all dataset. In this paper, we look at what is this problem, and propose the clustering of B-Trans to solve the problem. As we reduce more effectively the fairly large size created by FP-Tree by using B-Trans , memory size is decreased and the performance of creating rules is enhanced. |
