Yinhao Lu, Buyang Cao, Cesar Rego, Fred Glover

摘要:

著名的K-means聚类算法已广泛应用于从数据分析到物流应用的不同应用领域。然而,K-means算法可能会受到诸如初始质心选择等因素的影响,并且很容易陷入局部最优。本文提出了一种改进的K-means聚类算法,该算法通过Tabu搜索策略进行了扩展,更好地适应了大数据应用的需求。我们的设计进一步增强,以利用基于Spark框架的并行处理。计算实验证明了我们的禁忌搜索的聚类算法的优越性,在广泛使用的版本的K-means方法体现在Spark MLlib,比较算法的可扩展性,准确性和有效性。

英文摘要:

The well-known K-means clustering algorithm has been employed widely in different application domains ranging from data analytics to logistics applications. However, the K-means algorithm can be affected by factors such as the initial choice of centroids and can readily become trapped in a local optimum. In this paper, we propose an improved K-means clustering algorithm that is augmented by a Tabu Search strategy, and which is better adapted to meet the needs of big data applications. Our design is further enhanced to take advantage of parallel processing based on the Spark framework. Computational experiments demonstrate the superiority of our Tabu Search based clustering algorithm over a widely used version of the K-means approach embodied in Spark MLlib, comparing the algorithms in terms of scalability, accuracy, and effectiveness.
