基于商空间理论层次Cube操作的聚集算法研究

Research of Aggregate Algorithin of Hierarchical Cube Operation Based on Theory of Quotient Space

传统的Cube计算算法对具有复杂维层次结构的多维数据集合实施Cube操作时,存在明显的不足.提出了基于商空间理论层次Cube操作的聚集算法.结果表明,其在性能测试中较传统的算法在计算效率方面有了显著的提高.

As the shortage of traditional cube algorithm computing data set of complex dimension hierarchy, this parper introduces an aggregate algorithm of an aggregate algorithm of hierachical cube operation based on theory of quotient space. The experiments show that this algorithm performs more effectively computation performance than traditional one.
