WebSurveys for SOM quality measures are generally rare in literature. Earlier approaches have been mainly concerned with finding energy functions for the SOM [10, 19]. Usually, whenever a new method for quantifying the quality of the SOM is pr oposed, it is compared to existing ones, and a short overview is presented in the introductions [2, 8]. WebOrganizing Map (SOM), vector quantization, PCA, Indepen-dent Component Analysis (ICA), Isomap, and Non-negative Matrix Factorization (NMF). Only a few of these algorithms have been expressed by in-place versions (e.g., SOM and PCA [11]).
