Pseudocode of Intracluster compactness.
) Input: Data set , the total number of points n, the number of clusters K, | the clustering result , K-1 inconsistent edges , the | geodesic distance between points xi and xj | ) Output: Intracluster compactness CP | ) Begin | Sort the pairwise geodesic distances of all points from | Extract the top 20% maximum geodesic distance (here, suppose there are a total of | maximum geodesic distances) | Calculate the average of the maximum geodesic distances | Calculate the intracluster distance for the , | Calculate | Calculate the intracluster compactness of data set X, ( is the weight of Clusteri) | ) End |
