Parallel centroid-based clustering method is proposed to determine the final clustering result. The clustering results are visualized with interpolation MDS dimension reduction method. The efficiency of the method is illustrated with a practical DNA clustering example.doi:10.1007/s11227-014-1174-1...
[12] proposed a Generalized Cluster Centroid-Based Classifier (GCCC) that exploits a clustering algorithm to integrate KNN and Rocchio algorithm. In fact, the skewed distribution of data is the main reason that leads to the misfit of CBC. Thus, the improvements that focus on the adjustment of...
We study several centroid based clustering algorithms in the context of alignment-free sequence comparison. From the point of view of these algorithms each sequence is represented by the vector of the word (n-mer) counts. We restrict ourselves to the case of the relatively short sequences, havi...
Cluster analysis is a method of organizing data into representative groups based upon similar characteristics. Each member of the cluster has more in common with other members of the same cluster than with members of the other groups. The most representative point within the group is called the ...
7.1 k-Means Clustering k-Means clustering is a prototype-based clustering method where the dataset is divided into k-clusters. k-Means clustering is one of the simplest and most commonly used clustering algorithms. In this technique, the user specifies the number of clusters (k) that need to...

Here, we focus on demonstrating a quantum analog of the Nearest Centroid algorithm, a simple similarity-based classification technique, which is also used in clustering algorithms in unsupervised learning. The Nearest Centroid algorithm is a good baseline classifier that offers interpretable results, thou...
