Topographic error

A Self-Organizing Map (SOM) has good quality when both of its measures, quantization error (QE) and topographic error (TE), are small. Many researchers have tried to reduce these measures by improving SOM’s learning algorithm, however, most results only decrease either QE or TE. In this paper, a method to improve the quality of the map obtained when the SOM’s learning algorithm ended is proposed.
