Algorithms for Data Cube-Based Intra-dimensional Association Rules Mining
-
摘要: 針對數據立方體的結構特點,結合聯機分析處理技術,提出了兩種基于數據立方體的維內關聯規則挖掘算法.以合肥農河超市實際數據作為測試數據,給出了兩種算法的實驗結果.結果表明,兩種算法在不同支持度情況下執行效率存在明顯差異,分別適合在高支持度和低支持度情況下進行關聯規則挖掘.Abstract: Two algrithms for data cube-based intra-dimensional association rules mining are proposed by lucubrating into the structure of data cube and integrating with the technology of online analytical processing. Experiment results show that the two algorithms are respectively suitable for different support-constrained association rules mining.
