Optimized spiral spherical self-organizing map approach to sector analysis – The case of banking

作者：

Highlights：

• Optimized spiral spherical self-organizing map is applied to real-life data.

• We investigate the European Union banking sector in the 2000–2011 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.
