About the clustering method, I use SOM (self-organizing map), with 2 dimensions (as far as I know, there is no convergence theorem with the 2d (there exists in 1d), and I compare the SOM with k-means, spectral, and other methods. Concerning the number of cluster, I already concidered different values of the number of clusters. It's kinda weird but I need to concider at least 100 clusters, but SOM and kmeans perfomed better for less. | |
