- W2895599258 abstract "K-means is a popular and simple clustering method by grouping data into predefined K clusters efficiently. However, K-means performs poorly in the presence of poor centers and tends to converge prematurely. Hydrologic Cycle Optimization, as a novel algorithm inspired by the natural phenomena, has a good ability to search for the global optimal solutions. To overcome drawbacks associated with the K-means and find better initial centroids, in this study, a hybrid clustering algorithm based on Hydrologic Cycle Optimization and K-means (abbreviated as HCO+K-means) is proposed. The proposed algorithm includes two modules: HCO module and K-means module. It executes HCO module firstly to find the best individual with optimal fitness value. While the position of the best individual is then considered as initial set of centers for K-means module to search for a higher quality clustering solution. For comparison purpose, the K-means, PSO+K-means, WCA+K-means and HCO+K-means algorithms are chosen to evaluate on six different datasets. The experimental results indicate that the proposed HCO+K-means algorithm has a strong global search ability and obtains better clustering results in comparison to the other clustering methods." @default.
