Clustering by Fuzzy Neural Gas and Evaluation of Fuzzy Clusters

Figure 1

Prototype update Neural Gas (a) versus Pulsing Neural Gas (b). NG: the closer the prototype the lower its rank and the stronger the update in direction of the data point. PNG: at random time steps negative learning is performed. The closer the prototype the higher its rank and the weaker the update in the opposite direction of the data sample.
