ALMOST OPTIMAL SOLUTIONS TO k-CLUSTERING PROBLEMS
International Journal of Computational Geometry & Applications, 2010We implement an algorithm for k-clustering for small k in fixed dimensions and report experimental results here. Although the theoretical bounds on the running time are hopeless for 1 + ∊ approximating k-clusters, we note that for dimensions 2 and 3, k-clustering is practical for small k (k ≤ 4) and simple enough shapes. For the purposes of this paper,

Global optimization of clustering problems
2022Clustering is a fundamental unsupervised machine learning task that aims to aggregate similar data into one cluster and separate those in diverse into different clusters. Cluster analysis can always be formulated as an optimization problem. Various objective functions may lead to different clustering problems.

Cluster analysis problems and bio-inspired clustering methods
2017 XX IEEE International Conference on Soft Computing and Measurements (SCM), 2017The article presents the analysis of the clustering problem formalization and considers possibilities to use the classical methods and bio-inspired methods for solving problems of the cluster analysis. In this paper we do not present full review of the new clustering methods, but identify some trends in the development of cluster analysis and special ...

CLUSTERING PROBLEMS FOR HIGH DIMENSIONAL DATA
2014We consider a clustering problem where we observe feature vectors Xi ∈ Rp , i = 1, 2, . . . , n, from several possible classes. The class labels are unknown and the main interest is to estimate these labels. We propose a three-step clustering procedure where we first evaluate the significance of each feature by the Kolmogorov-Smirnov statistic, then we
