Efficiency of Random Sampling Based Data Size Reduction on Computing Time and Validity of Clustering in Data Mining

In data mining, cluster analysis is one of the widely used analytics to discover existing groups in datasets. However, the traditional clustering algorithms become insufficient for the analysis of big data which have been formed with the enormous increase in the amount of collected data in recent ...

A Programmatic Implementation of the Visual Assessment of Cluster Tendency Algorithm in R

In cluster analysis, the partitioning algorithms require a priori estimate of number of clusters (c) as an input parameter, and thus the success of partitioning depends mostly on this parameter. In order to find an optimal c, the obtained results are checked by the various cluster validity indices a...

Computing Performance and Clustering Validity Comparison of Fuzzy C-means Algorithm for Different Cluster Volumes

Clustering is an unsupervised classification to assign similar data elements into certain groups, called clusters. Each cluster consists of elements that are more similar to each others when compared to elements in other groups. Although they can be categorized in several ways, clustering methods ca...
