Using the Kohonen Network to Group World Economies in the Context of Factors Characterizing the Meeting of their Energy Needs

Abstract
The purpose of the paper is clustering world economies in the context of factors characterizing the meeting of their energy needs. To achieve this purpose the Kohonen network was used, which realizes unsupervised learning (self-learning) network (SOM). The necessary computations were performed using the som () function of class package running in the R environment. The result of the clustering analysis was obtaining homogeneous groups of states worldwide. It can serve further elaborations over improving the meeting of Poland’s energy needs.
