Performance study of distributed Apriori-like frequent itemsets mining
Knowledge and Information Systems, 2010
In this article, we focus on distributed Apriori-based frequent itemsets mining. We present a new distributed approach which takes into account inherent characteristics of this algorithm. We study the distribution aspect of this algorithm and give a comparison of the proposed approach with a classical Apriori-like distributed algorithm, using both analytical and experimental studies. We find that under a wide range of conditions and datasets, the performance of a distributed Apriori-like algorithm is not related to global strategies of pruning since the performance of the local Apriori generation is usually characterized by relatively high success rates of candidate sets frequency at low levels which switch to very low rates at some stage, and often drops to zero. This means that the intermediate communication steps and remote support counts computation and collection in classical distributed schemes are computationally inefficient locally, and then constrains the global performance. Our performance evaluation is done on a large cluster of workstations using the Condor system and its workflow manager DAGMan. The results show that the presented approach greatly enhances the performance and achieves good scalability compared to a typical distributed Apriori founded algorithm.

The best known such task is the association rules finding. Since its inception, many frequent itemset mining algorithms have been proposed in the literature [1-5], etc. Many of them are related to the Apriori approach. Basically, frequent itemsets generation algorithms analyse
ParallelCharMax: An Effective Maximal Frequent Itemset Mining Algorithm Based on MapReduce Framework
—Nowadays, the explosive growth in data collection in business and scientific areas has required the need to analyze and mine useful knowledge residing in these data. The recourse to data mining techniques seems to be inescapable in order to extract useful and novel patterns/models from large datasets. In this context, frequent itemsets (patterns) play an essential role in many data mining tasks that try to find interesting patterns from datasets. However, conventional approaches for mining frequent itemsets in Big Data era encounter significant challenges when computing power and memory space are limited. This paper proposes an efficient distributed frequent itemset mining algorithm, called ParallelCharMax, that is based on a powerful sequential algorithm, called Charm, and computes the maximal frequent itemsets that are considered perfect summaries of the frequent ones. The proposed algorithm has been implemented using MapReduce framework. The experimental component of the study shows the efficiency and the performance of the proposed algorithm compared with well known algorithms such as MineWithRounds and HMBA.

The traditional datamining is based on the fp growth algorithm focused on the load balancing, and distributed among the nodes of the clusters.The process is mainly based on mapreduce which highly supported by Hadoop.Hadoop is a efficient popular frame work which supports mapreduce and itemset mining .Map reduce is that which contains map phase and reduce phase.Map phase which results the pair of key values and reduce phase which results the reduced results. It aims to decrease network overhead and efficient processing.
An Efficient Implementation of Apriori Algorithm Based on Hadoop-Mapreduce Model
2012
Finding frequent itemsets is one of the most important fields of data mining. Apriori algorithm is the most established algorithm for finding frequent itemsets from a transactional dataset; however, it needs to scan the dataset many times and to generate many candidate itemsets. Unfortunately, when the dataset size is huge, both memory use and computational cost can still be very expensive. In addition, single processor’s memory and CPU resources are very limited, which make the algorithm performance inefficient. Parallel and distributed computing are effective strategies for accelerating algorithms performance. In this paper, we have implemented an efficient MapReduce Apriori algorithm (MRApriori) based on HadoopMapReduce model which needs only two phases (MapReduce Jobs) to find all frequent k-itemsets, and compared our proposed MRApriori algorithm with current two existed algorithms which need either one or k phases (k is maximum length of frequent itemsets) to find the same freq...

A Survey on Frequent Item sets Mining for Big Data
Bulletin of the Faculty of Engineering. Mansoura University, 2020
Big Data" connects large-volume, complex, and increasing data sets with multiple independent sources. Nowadays, Big Data are speedily expanding in all science and engineering domains due to the rapid evolution of data, data storage, and the networking collection capabilities. Due to its variability, volume, and velocity, "Big Data mining" enjoys the ability of extracting constructive information from huge streams of data or datasets. Data mining includes exploring and analyzing big quantities of data in order to locate different molds for big data. "Frequent item sets Mining" is one of the most important tasks for discovering useful and meaningful patterns from large collections of data. Mining of association rules from frequent patterns from big data mining is of interest for many industries, for it can provide guidance in decision making processes; such as cross marketing, market basket analysis, promotion assortment, ...etc. The techniques of discovering association rules from data have traditionally focused on identifying the relationship between items predicting some aspect of human behavior; usually buying behavior.
