Enhanced Initial Centroids for K-means Algorithm

By Aleta C. Fabregas Bobby D. Gerardo Bartolome T. Tanguilig III

DOI: https://doi.org/10.5815/ijitcs.2017.01.04, Pub. Date: 8 Jan. 2017

This paper focuses on the enhanced initial centroids for the K-means algorithm. The original k-means is using the random choice of initial seeds which is a major limitation of the original K-means algorithm because it produces less reliable result of clustering the data. The enhanced method of the k-means algorithm includes the computation of the weighted mean to improve the centroids initialization. This paper shows the comparison between K-Means and the enhanced K-Means algorithm, and it proves that the new method of selecting initial seeds is better in terms of mathematical computation and reliability.
