The PCASOM is a novel self-organizing neural model that performs Principal Components Analysis (PCA). It is also related to the ASSOM network, but its training equations are simpler. The PCASOM has the ability to learn self-organizing maps of the means and correlations of complex input distributions. Here we propose a method to extend this capability to build intrinsic dimensionality maps. These maps model the underlaying structure of the input. Experimental results are reported, which show the self-organizing map formation performed by the proposed network.
