Clustering performance comparison between SCC and SSCC with varied subsampling rates in five datasets

Clustering accuracy using SCC and SSCC was measured at various subsampling rates of the original data in the five datasets, i.e., the percentage of cells used in clustering. The clustering accuracy is indicated using NMI. For each subsampling rate, calculations were repeated for ten times, based on which the average and the standard deviation of the clustering accuracy were calculated and plotted. NMI, normalized mutual information; SSCC, Spearman subsampling-clustering-classification; AP, affinity propagation.
