Data Mining By Parallelization of Fp-Growth AlgorithmIn this paper we present idea to make one main tree on master node and slave do processing with database rather than have multiple FP-trees, one for each processor Firstly, the dataset is divided equally among all participating processors Pi....
A variety of algorithms have been proposed for mining frequent item sets. The proposed method implements PFP growth algorithm, which performs pre- processing to improve the utility and privacy trade-off and novel splitting algorithm, to support transformation in the database. To improve the utility...

Abstract:In order to improve the accurate detection and recognition ability of abnormal data in ground meteorological observation sets,a ground meteorological observation data anomaly mining method based on FP-Growth algorithm is proposed.Set the frequency of data collection,determine the time interval for...
数据挖掘(DataMining)最早的研究可以追溯到数十年 前,从20世纪80年代就出现了知识发现及数据挖掘的研 究 [2] ,其中的关联规则挖掘算法(AssociationRuleMining Algorithm)被用来发现大量数据中项集之间有趣的关联或相 关联系,是数据挖掘中的重要课题之一,最近几年已被业界所 广泛应用和研究。关联规则挖掘算法中比较经...
Big data and data mining have a significant influence on the development and progress of China and every trade and many domains, and it is one of the directions that scholars are trying to study and apply. The most classical algorithm in the field of association rule mining is Apriori, ...
