Clustering Library (ClusteringLib)


getSSE
to calculate sum of squared error of clusters



FUNCTIONS

double - getSSE(int[][] data, int[] clusters)
double - getSSE(double[][] data, int[] clusters)
double - getSSE(int[][] data, double[][] centroids)
double - getSSE(double[][] data, double[][] centroids)




EXAMPLES

Example	VectorLib vlib=new VectorLib(); ClusteringLib clib=new ClusteringLib(); int[][] data={{20, 30}, {30, 20}, {30, 30}, {70, 70}, {80, 80}}; int[] clusters=clib.Clustering("kmeans", data, 2); double sse=clib.getSSE(data, clusters); vlib.view("SSE", sse);
Output	SSE = 6.752660136327973
