Several attempts were made by researchers for improving the performance of the k-means clustering algorithm. This paper deals with a method.

Abstract: Data mining has been defined as "The nontrivial extraction of implicit, previously unknown, and potentially useful information from data". Clustering is the automated search for group of related observations in a data set. The K-Means method is one of the most commonly used clustering techniques for a variety of.

K*-Means: An Effective and Efficient K-Means Clustering Algorithm. Abstract: K-means is a widely used clustering algorithm in field of data mining across different disciplines in the past fifty years. However, k-means heavily depends on the position of initial centers, and the chosen starting centers randomly may lead to poor.

Dec 19, 2017 . In this paper, we present a simple and efficient clustering algorithm based on the k-means algorithm, which we call enhanced k-means algorithm. . are different. Clustering has been a widely studied. problem in a variety of application domains including. data mining and knowledge discovery (Fayyad et al.,.

k-means algorithm is one of the basic clustering techniques that is used in many data mining applications. In this paper we present a novel pattern . Today, we are capable of generating location information for mobile users, cars, buses, planes, animals, and other moving objects. This proliferation in location information.

k-means clustering is a method of vector quantization, originally from signal processing, that is popular for cluster analysis in data mining. k-means clustering aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean, serving as a prototype of the cluster. This results.

CLUSTERING problems arise in many different applica- tions, such as data mining.

Aug 31, 2017 . K-means plays an important role in different fields of data mining. However, k-means often becomes sensitive due to its random seeds selecting. Motivated by this, this article proposes an optimized k-means clustering method, named k*-means, along with three optimization principles. First, we propose a.

The proposed scheme is then simulated using the K-means clustering algorithm, which is one of the most popular clustering algorithms to.

Nov 6, 2014 . Clustering is an important means of data mining based on separating data categories by similar features. Unlike the classification algorithm, clustering belongs to the unsupervised type of algorithms. Two representatives of the clustering algorithms are the K-means and the expectation maximization (EM).

K-means algorithm is a simple technique that partitions a dataset into groups of sensible patterns. It is well known for clustering large datasets and generating effective results that are used in a variety of scientific applications such as Data Mining, knowledge discovery, data compression, vector quantization and medical.

measure to determine the number of clusters for the K-means algorithm for different data sets. . data-mining or data analysis software packages . No attention is paid to the effect of the clustering results on the performance of this algorithm. In such applications, the K-means algorithm is employed just as a 'black box'.

Data Mining, Clustering, K-Means Clustering Algorithm. . the cluster objects. If the distance between the two objects is less then that objects are more similar to each other whereas if the distance between the two objects is more then that objects are .. algorithm more effective and efficient; so as to get better clustering.

Experiments show the efficiency of the proposed strategy when applied to different data sets. Key words: clustering, k-means algorithm, pattern recognition, partial distance. INTRODUCTION. Clustering techniques have become very popular in a number of areas, such as engineering, medicine, biology and data mining[1,2].

carried out as a preprocessing step. The standard k-means algorithm [5, 8] for cluster analysis developed for low dimensional data, often do not work well for high dimensional data and the results may not be accurate most of the time due to noise. Different methods have been proposed [1] by combining PCA with k- means.

used to cluster categorical data. The algorithm, called k- modes, is an extension to the well known k-means algorithm (MacQueen 1967). Compared to other clustering methods the k-means algorithm and its variants. (Anderberg 1973) are efficient in clustering large data sets, thus very suitable for data mining. However, their.
