Aug 11, 2018The k-means clustering is one of the most widely used techniques in data mining [11, 16, 2, 20, 15].The k-means clustering algorithm is used to find groups which have not been explicitly labeled in the data. This can be used to confirm business assumptions about what types of groups exist or to identify unknown groups in complex data sets.

Therefore, this paper is using k-means clustering algorithm, which is used to decide the ideal cluster center, so it can be the cluster centroid. Furthermore, the Nave Bayes algorithm of classification process is applied for the academic evaluation data to generate rules which are studied and evaluated to predict the educational performance.

—Recent advances in sensing and storing technologies have led to big data age where a huge amount of data are distributed across sites to be stored and analysed. Indeed, cluster analysis is one of the data mining tasks that aims to discover patterns and knowledge through different algorithmic techniques such as k-means. Nevertheless, running k-means over distributed big data stores has given
