Frequency distribution of samples in SOM grid and optical number of clusters. a SOM grid. The numbers on the left and right were the sequence numbers of 105 neurons. b Number of samples in each neuron. Seven neurons were dead neurons (i.e., neurons that never won the competition for samples). c Determining the optical number of clusters using the majority rule and 20 indices
