Modern hierarchical, agglomerative clustering algorithms

In data mining and statistics, hierarchical clustering (also called hierarchical cluster analysis or HCA) is a method of cluster analysis that seeks to build a hierarchy of clusters. Strategies for hierarchical clustering generally fall into two categories: • Agglomerative: This is a "bottom-up" approach: Each observation starts in it… Web1 de jul. de 2024 · The wireless sensor network (WSN) has attracted much research interest due to its many potential applications in different fields.
