Abstract
The agglomerative hierarchical clustering algorithm is introduced in this paper based on the standard algorithm.Through sorting the distance between clusters to avoid recomputing the distance between clusters we proposed the improved algorithm,which decreases the complexity.According to the experiment,the improved algorithm has the same clustering results as the standard agglomerative hierarchical clustering algorithm,but the speed is higher.
