分布式空间数据聚类--大数据分析的新方法

Distributed Spatial Data Clustering as a New Approach for Big Data Analysis

Malika Bendechache, Nhien-An Le-Khac, M-Tahar Kechadi

摘要:

本文提出了一种新的大数据采掘和分析方法。这种新方法适用于分布式数据集,并处理数据聚类分析任务。该方法由两个主要阶段组成,第一阶段对本地数据执行聚类算法,假设数据集已经分布在系统处理节点之间。第二阶段处理局部聚类聚合以生成全局聚类。这种方法不仅可以在每个处理节点上并行生成局部聚类,而且可以在不需要事先知道聚类数目的情况下生成全局聚类,而这是许多划分聚类算法所需要的。在这项研究中,这种方法被应用于空间数据集。所提出的聚合阶段是非常有效的,并且不涉及处理节点之间的大量数据的交换。实验结果表明,该方法具有超线性的加速性能,可扩展性好,且不受通信类型的影响,可以充分利用MapReduce等最新的编程模型。

英文摘要:

In this paper we propose a new approach for Big Data mining and analysis. This new approach works well on distributed datasets and deals with data clustering task of the analysis. The approach consists of two main phases, the first phase executes a clustering algorithm on local data, assuming that the datasets was already distributed among the system processing nodes. The second phase deals with the local clusters aggregation to generate global clusters. This approach not only generates local clusters on each processing node in parallel, but also facilitates the formation of global clusters without prior knowledge of the number of the clusters, which many partitioning clustering algorithm require. In this study, this approach was applied on spatial datasets. The proposed aggregation phase is very efficient and does not involve the exchange of large amounts of data between the processing nodes. The experimental results show that the approach has super linear speed up, scales up very well, and can take advantage of the recent programming models, such as MapReduce model, as its results are not affected by the types of communications.
