WebCombining Clusters in the Agglomerative Approach. In the agglomerative hierarchical approach, we define each data point as a cluster and combine existing clusters at each step. Here are four different methods for this approach: Single Linkage: In single linkage, we define the distance between two clusters as the minimum distance between any ... WebTools. In statistics, single-linkage clustering is one of several methods of hierarchical clustering. It is based on grouping clusters in bottom-up fashion (agglomerative clustering), at each step combining two clusters that contain the closest pair of elements not yet belonging to the same cluster as each other.
