Optimized spiral spherical self-organizing map approach to sector analysis  The case of banking
Optimized spiral spherical self-organizing map is applied to real-life data. We investigate the European Union banking sector in the 20002011 period. We use micro and macro economic data for two separate models. Both models reveal the existence of two separate banking clusters. Dynamic analysis indicates intensification of integration within the two groups.
