挖掘频繁项集是数据挖掘应用中关键的问题。经典的FP-growth 算法利用FP-tree 有效的压缩了数据集的规模,但是在挖掘过程中需要反复递归构造条件FP-tree 成为限制算法效率的瓶颈。...
为发挥各种网络安全技术联合优势,提出基于日志的联动控制,采用FP-growth算法挖掘关联规则频繁项集,并对该算法进行优化,实现联合检测和防御,增强了企业网络的抗攻击和抵御威胁能力。此外,鉴于...
在数据库中发现频繁模式和关联规则是数据挖掘领域的最基本、最重要的问题。大多数早期的研究采用了类似Apriori算法的产生候选级并测试迭代的途径代价是昂贵的,尤其是挖掘富模式和长模式时,Jiawei Han提出了一种新颖的数据结构FP_tree,及基于其上的FP_growth算法,主要用于有效的进行长...
Digital mobile wireless communication and the Internet have undergone a fantastic growth in the last few years and, despite originating from two diffe...
