Web9 de mai. de 2024 · How does the Hierarchical Agglomerative Clustering (HAC) algorithm work? The basics. HAC is not as well-known as K-Means, but it is quite flexible and often easier to interpret. It uses a “bottom-up” approach, which means that each observation starts in its own cluster, and pairs of clusters are merged as one moves up the hierarchy.
