提出一种基于强关联规则的可行动分簇算法(AC-SAR)。AC-SAR算法为每一个对象寻找关联性最强的对象,并通过反对称原则和可连接原则删除和合并相应规则,最终挖掘出涉及事务数据库中所有对象的多个连通子图(簇)。与传统算法相比,新算法无需设置阈值,没有冗余知识,算法的中间挖掘结果及最终生成的簇,能有效地解决诸多领域的实际问题。大量试验结果表明,该新算法具有较高的效率、准确性以及较强的可行动性。
An actionable clustering algorithm based on strong association rules (AC-SAR)was proposed.The AC-SAR algorithm looked for strong associated objects for each object,and then some relevant rules were deleted and merged by the anti-symmetric principle and the connectivity principle.The connected sub-graphs (clusters)related to all objects in transaction database were discovered finally.Compared with the traditional algorithms,the AC-SAR algo-rithm did not need to set the thresholds by user,and there were not redundant rules in the results.Moreover,the inter-mediate mined results and the final generated clusters could solve the problems in many fields effectively.A large number of experiments showed that the AC-SAR algorithm had higher efficiency,higher accuracy,and stronger action.
