WebMay 7, 2024 · Hierarchy-based algorithms include robust clustering using links (ROCK) and clustering using representatives (CURE) , etc. The hierarchy-based algorithms build a hierarchical relationship among samples to conduct clustering. The hierarchy-based algorithms also need to predefine the number of clusters. Webpoints. Squeezer [23] is a categorical clustering algorithm that processes one point at the time. At each step, a point is either placed in an existing cluster or it is rejected by all clusters and it creates a new one. The decision is based on a given similarity function.
