摘要:
文中基于对传统Apriori算法的改进,提出了一种基于规则的离群数据挖掘算法。该算法在数据结构中增加标识符链表后,计算了1-离群条件集的幂集,使得仅需对原数据库进行一次扫描,从而降低了该算法的时间复杂度。同时由于兴趣度的引入使得挖掘的结果也更有针对性和目的性。该算法被应用于某求职系统的离群数据分析中,实验表明该算法是可行有效的
Abstract:
An improved rule - based outlier mining algorithm is proposed in this paper based on the conventional Apriori algorithm. In this algorithm, after the identifier linked lists being added to the data structure, the power set of 1 - outlier - rules is formed. Only one scanning of the data source is needed using this method, which reduces the time complexity of this algorithm distinctly. The introduction of the degree of interest also makes the results more pertinent and reasonable. This algorithm has been used in the analysis of a real - world job - hunting system. It exhibits satisfiable performance
