چکیده

The K-Modes clustering algorithm [1] has shown great promise for clustering large data sets with categorical attributes. K-Mode clustering algorithm suffers from the drawback of choosing random selection of initial points (modes) of the cluster. Different initial points leads to different cluster formations. In this paper Density-based Multiscale Data Condensation [2] approach with hamming distance [1] is used to extract K-initial points. Experiments show that K-modes clustering algorithm using these initial points produce improved and consistent results then the random selection method.

Density-Based Multiscale Data Condensation

ÐA problem gaining interest in pattern recognition applied to data mining is that of selecting a small representative subset from a very large data set. In this article, a nonparametric data reduction scheme is suggested. It attempts to represent the density underlying the data. The algorithm selects representative points in a multiscale fashion which is novel from existing density-based approa...

Entropy-based Consensus for Distributed Data Clustering

The increasingly larger scale of available data and the more restrictive concerns on their privacy are some of the challenging aspects of data mining today. In this paper, Entropy-based Consensus on Cluster Centers (EC3) is introduced for clustering in distributed systems with a consideration for confidentiality of data; i.e. it is the negotiations among local cluster centers that are used in t...

High-Dimensional Unsupervised Active Learning Method

In this work, a hierarchical ensemble of projected clustering algorithm for high-dimensional data is proposed. The basic concept of the algorithm is based on the active learning method (ALM) which is a fuzzy learning scheme, inspired by some behavioral features of human brain functionality. High-dimensional unsupervised active learning method (HUALM) is a clustering algorithm which blurs the da...

ارائه یک الگوریتم خوشه بندی برای داده های دسته ای با ترکیب معیارها

Clustering is one of the main techniques in data mining. Clustering is a process that classifies data set into groups. In clustering, the data in a cluster are the closest to each other and the data in two different clusters have the most difference. Clustering algorithms are divided into two categories according to the type of data: Clustering algorithms for numerical data and clustering algor...
