Wavelet Based Fuzzy Clustering of Higher Dimensional Data

C. Palanisamy, S. Selvan

Abstract


In this paper, an approach for automatically clustering a data set into a number of fuzzy partitions with wavelets is proposed. This is an improved version of fuzzy clustering scheme in which fuzzy ant algorithm is utilized to give better initialization and thus the clustering performance. Appropriate subbands are selected and clustered. The effectiveness of the proposed technique is studied using various validity measures such as partition coefficient, classification entropy, separation index and Xie-Beni index. The experiments are carried out using both artificial and real-life data sets and it is found that our approach performs better than other approaches.

We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information.
