Kohonen Map

This article deals with evaluation of consumer data by Artificial Intelligence methods. In methodical part there are described learning algorithms for Kohonen maps on the principle of supervised learning, unsupervised learning and semi-supervised learning. The principles of supervised learning and unsupervised learning are compared. On base of binding conditions of these principles there is pointed out an advantage of semi-supervised learning. Three algorithms are described for the semi-supervised learning: label propagation, self-training and co-training. Especially usage of co-training in Kohonen map learning seems to be promising point of other research. In concrete application of Kohonen neural network on consumer’s expense the unsupervised learning method has been chosen – the self-organization. So the features of data are evaluated by clustering method called Kohonen maps. These input data represents consumer expenses of households in countries of European union and are characterised by 12-dimension vector according to commodity classification. The data are evaluated in several years, so we can see their distribution, similarity or dissimilarity and also their evolution. In the article we discus other usage of this method for this type of data and also comparison of our results with results reached by hierarchical cluster analysis.

In this paper, we present some Bentham’s theory features that make him precursor of marginalist economics. The author described the ideas of decreasing marginal utility and equimarginality, he made a commodity classification that distinguished between an upper and a lower class of goods depending on the proximity to use and his defi-nition of property as an expectation of possession lead him to develop an economic theory based on individual information search. At the same time, he attached special importance to the figure of the innovative entrepreneur and described the market as a discovery process in which the central agent is the entrepreneur. Key words: Bentham, marginalist economics, entrepreneur. Clasificación JEL: B12. Resumen: En este artículo, se demuestra que la teoría de Jeremy Bentham es precursora de la economía marginalista. El autor intro-dujo las ideas de utilidad marginal decreciente, la equimarginalidad en el intercambio, realizó una clasificación entre bienes superiores e inferiores y su definición de la propiedad como una expectativa de pose-sión le llevó a desarrollar una teoría económica basada en la búsqueda individual de información. Así mismo, dio especial importancia a la figura del empresario innovador y describió el mercado como un pro-ceso de descubrimiento en que el agente central es el empresario. Palabras clave: Bentham, economía marginalista, empresario.
