Cluster analysis - Wikipedia
WEBCluster analysis refers to a family of algorithms and tasks rather than one specific algorithm. It can be achieved by various algorithms that differ significantly in their understanding of what constitutes a cluster and how to efficiently find them.
What Is Cluster Analysis? (Examples + Applications) - Built In
WEBMar 7, 2023 · Cluster analysis is a data analysis method that clusters (or groups) objects that are closely associated within a given data set. When performing cluster analysis, we assign characteristics (or properties) to each group. Then we create what we call clusters based on those shared properties.
