Examples
- Paper presentes a new algorithm of mining frequent item sets with negative items
论文提出一种新的挖掘含负项目的频繁项集算法,即基于频繁模式树的算法。 - In addition , the paper discusses the contradictions of generalizing associaton rules with negative items
论文另外对含负项目的一般化关联规则的矛盾性进行了讨论。 - At present , positive association rules have been widely concerned , but association rules with negative attributes or negative items are not given sufficient attentiones
当前,正关联规则的挖掘受到了广泛的关注,而对于包含负属性或负项目的关联规则并未给予足够的重视。 - Based on the confidence property and interest threshold , this paper uses for reference apriori algorithm and makes a method for extracting out generalizing associaton rules with negative items from the frequent itemsets with negative items
论文基于置信度性质和兴趣度阈值,并借用apriori算法,从挖掘出的含负项目的频繁项集中提取出含负项目的一般化关联规则。 - The algorithm is based on the frequent pattern tree , which uses for reference a compressed storage data structure i . e . frequent pattern tree of fp _ growth algorithm . it mines frequent item sets with negative items through extending frequent patterns on the tree
该算法借用fp _ growth算法中频繁模式树这种压缩存储事务的数据结构,通过频繁模式树进行模式扩展,挖掘含负项目的频繁项集。
