Optimized K-Means Clustering Model based on Gap Statistic

Big data has become famous to process, store and manage massive volumes of data. Clustering is an essential phase in big data analysis for many real-life application areas uses clustering methodology for result analysis. The data clustered sets have become a challenging issue in the field of big data analytics. Among all clustering algorithm, the K-means algorithm is the most widely used unsupervised clustering approach as seen from past. The K-means algorithm is the best adapted for deciding similarities between objects based on distance measures with small datasets. Existing clustering algorithms require scalable solutions to manage large datasets. However, for a particular domain-specific problem the initial selection of K is still a significant concern. In this paper, an optimized clustering approach presented which is calculated the optimal number of clusters (k) for specific domain problems. The proposed approach is an optimal solution based on the cluster performance measure analysis based on gab statistic. By observation, the experimental results prove that the proposed model can efficiently enhance the speed of the clustering process and accuracy by reducing the computational complexity of the standard k-means algorithm which achieves 76.3%.
