Abstract
W artykule badamy sprawność algorytmu wybierania zmiennych w analizie skupień opartego na entropii (por. Dash. Liu. 2000). Ocena oparta jest na eksperymencie, w którym zbiory generowane są w postaci mieszanin rozkładów normalnych. Wyniki wskazują na to. że metoda nie radzi sobie tak dobrze jak to sugerowali Autorzy. (abstrakt oryginalny)

In the paper, we investigate the efficiency of an algorithm for the choice of variables in cluster analysis built on the entropy approach (Dash, Liu, 2000). The assessment of this algorithm is carried out on synthetic data sets in the form of the mixtures of normal distributions. It turns out that the method is not working so well as the Authors of the entropy based approach suggested. (original abstract)
