Clustering of Artificial Data Set using SPC and TRIBE-MCL algorithm. The red, blue and yellow colors correspond to three distributions used to generate the data. The noise between the data points from distributions 1 and 2 is indicated as green circles. A) Cluster size plot of SPC algorithm. The vertical line indicates temperature when calculation of the distance matrix B) was performed. B) The distance matrix calculated for the SPC clusters at temperature T = 0.087. More intense colors correspond to smaller distances between points. The diagonal and off-diagonal elements correspond to inter- and intra- cluster distances, respectively. Each horizontal block on the left side of Figure corresponds to one cluster and the colors are used to indicate composition of samples from different distributions. C) and D) are the distance matrices calculated for the TRIBE-MCL clusters obtained using inflation parameter 2.1 and 5.1, respectively.
