Clustering performance comparison usingK-means and expectation maximization algorithms

Abstract: Clustering is an important means of data mining based on separating data categories by similar features. Unlike the classification algorithm, clustering belongs to the unsupervised type of algorithms. Two representatives of the clustering algorithms are the K-means and the expectation maximization (EM) algorithm. Linear regression analysis was extended to the category-type dependent variable, while logistic regression was achieved using a linear combination of independent variables. To predict the possibility … Show more

“…A common technique to observe this dataset is using clustering. Clustering splits a large amount of data and performs grouping considering the similarities of the individual data supplied [2]. However, several clustering algorithms suffer from high computational cost and one of which is the Fuzzy C-Means algorithm.…”
