| Abstract: | The problem of mining association rules and its relative parallel mining algorithms is presented. The problems that existing algorithms can cause low efficiency and information lost in heterogeneous distributed databases is pointed out. An asynchronous parallel algorithm based on our HDDMiner system for mining association rules in heterogeneous distributed databases is given after a basic theory is proved. Some problems involved are discussed in detail as well. At the end of this paper, several key issues in the research of parallel algorithms in heterogeneous distributed databases are introduced. |
