Abstract

Clustering analysis has been considered as useful means for identifying patterns of dataset. The aim for this analysis is to decide what is the most suitable algorithm to be used when dealings with new scatter data. In this analysis, two important clustering algorithms namely fuzzy c-means and k-means clustering algorithms are compared. These algorithms are applied to synthetic data 2-dimensional dataset. The numbers of data points as well as the number of clusters are determined, with that the behavior patterns of both the algorithm are analyzed. Quality of clustering is based on lowest distance and highest membership similarity between the points and the centre cluster in one cluster, known as inter-class cluster similarity. Fuzzy c-means and k-means clustering are compared based on the inter-class cluster similarity by obtaining the minimum value of summation of distance. Additionally, in fuzzy c-means algorithm, most researchers fix weighting exponent (m) to a conventional value of 2 which might not be the appropriate for all applications. In order to find m, also called as fuzziness coefficient, optimal in fuzzy c-means on particular dataset is based on minimal reconstruction error.
