Snn shared nearest neighbor
WebSharing nearest neighbor (SNN) is a novel metric measure of similarity, and it can conquer two hardships: the low similarities between samples and the di erent densities of classes. At present, there are two popular SNN similarity based clustering methods: JP clustering and SNN density based clustering.
