Clustering Library (ClusteringLib)


getError
to calculate sum of squared error of clusters



FUNCTIONS

double - getError(int[] clusters, int[] label)




EXAMPLES

Example	VectorLib vlib=new VectorLib(); ClusteringLib clib=new ClusteringLib(); Dataset_int dataset=new Dataset_int("ruspini", "supervised"); double[][] centroids=clib.initCentroid(dataset.data, dataset.k); int[] clusters=clib.Clustering("kmeans", dataset.data, dataset.k); double error=clib.getError(clusters, dataset.label); vlib.view("Centroids awal", centroids); vlib.view("Error", error);
Output	Centroids awal = 52.0      90.0 90.0      6.0 32.0      75.0 81.0      56.0 Error = 33.333333333333336
