摘要
Although mining based on FP-Tree achieves high performance and efficiency, it still suffers from creating conditional FP-Tree separately and recursively during the mining process. Moreover, update mining is very time-consuming. In this paper, we propose a new method that designs a new structure called Trans-Tree, which stores all of the information in a highly compact form. The algorithm mines frequent patterns are based on Trans-Tree. Updating with new data needs one scan of the new data only. Thus, it improves performance greatly.
