IJCCS (Indonesian Journal of Computing and Cybernetics Systems), 2018

The implementation of parallel algorithms is very interesting research recently. Parallelism is very suitable to handle large-scale data processing. MapReduce is one of the parallel and distributed programming models. The implementation of parallel programming faces many difficulties. The Cascading gives easy scheme of Hadoop system which implements MapReduce model.Frequent itemsets are most often appear objects in a dataset. The Frequent Itemset Mining (FIM) requires complex computation. FIM is a complicated problem when implemented on large-scale data. This paper discusses the implementation of MapReduce model on Cascading for FIM. The experiment uses the Amazon dataset product co-purchasing network metadata.The experiment shows the fact that the simple mechanism of Cascading can be used to solve FIM problem. It gives time complexity O(n), more efficient than the nonparallel which has complexity O(n2/m).

Big dataextremely large data sets that may be analysed computationally to reveal patterns, trends, and associations, especially relating to human behaviour and interaction and the data mining used for dig deep into analyzing the patterns and relationships of data. Frequent item set mining is a data mining method that was developed for market basket analysis. In the project proposed to anefficient data processing using Lshfp growth algorithm and grouping similar objects as the clusters with group id. 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.

Review on Apriori Based Frequent Item Set Mining Using Various Techniques

International Journal for Research in Applied Science and Engineering Technology, 2018

Frequent Item set Mining is a standout amongst the most prominent systems to extract knowledge from data. Be that as it may, these mining strategies turn out to be more risky when they are connected to Big Data. Luckily, recent developments in the field of parallel programming give numerous devices to handle this issue. In any case, these instruments accompany their own technical difficulties, for example, balanced data distribution as well as inter-communication costs. In this paper, we are showing a point by point survey of Hadoop, which helps in putting away data and parallel processing in a distributed situation. Here we have surveyed different Frequent Item set Mining method on parallel and distributed condition. The point of this paper is to show a correlation of various frequent item set mining methods and help to create proficient and versatile frequent item set mining strategies.

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. Keywords Distributed data mining • Frequent itemsets generation • The Apriori algorithm • Grid computing 1 Introduction Mining frequent itemsets is at the core of various applications in the data-mining field.

— In this paper we introduce Traditional parallel algorithms for mining frequent itemsets aim to balance load by equally partitioning data among a group of computing nodes. Proposed system start this study by discovering a serious performance problem of the existing parallel Frequent Itemset Mining algorithms. Assign a large dataset, data partitioning strategies in the existing solutions suffer high communication and mining overhead induced by redundant transactions transmitted among computing nodes. This paper address problem by developing a data partitioning approach called FiDoop-DP using the MapReduce programming model. The Overall goal of FiDoop-DP is to boost the performance of parallel Frequent Itemset Mining on Hadoop clusters. At the heart of FiDoop-DP is the Voracity diagram-based data partitioning technique, which exploits correlations among transactions. Include the similarity metric and the Locality-Sensitive Hashing technique, FiDoop-DP places highly similar transactions into a data partition to improve locality without creating an excessive number of redundant transactions. This paper implement FiDoop-DP on a 24-node Hadoop cluster, driven by a wide range of datasets created by IBM Quest Market-Basket Synthetic Data Generator. Experimental results disclose that FiDoop-DP is conducive to decrease network and computing loads by the virtue of eliminating redundant transactions on Hadoop nodes. FiDoop-DP importantly improves the performance of the existing parallel frequent-pattern scheme by up to 31% with an average of 18%.

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.

Improving Efficiency of Parallel Mining of Frequent Itemsets using Fidoop-hd

2016

ARTICLE INFO Present parallel mining algorithms for frequent item sets lack a mechanism that enables automatic parallelization, load balancing, data administration, and fault liberality on large clusters. As a solution to this problem, design a parallel frequent item sets mining algorithm called Fidoop using the Map Reduce programming model. To achieve compressed storage and avoid building restrictive pattern bases, Fidoop incorporates the frequent items ultrametric tree, rather than regular FP trees. In Fidoop, two MapReduce jobs are implemented to complete the mining task. In the complex MapReduce job, the mappers independently decay item sets, the reducers perform combination operations by compressing data. This system implement Fidoop on private Hadoop cluster. This system show that Fidoop on the cluster is sensitive to data distribution and dimensions, because item sets with distinct lengths have different decaying and construction costs. In this paper system improve Fidoop’s p...
