WebIt attempts to preserve the same size for each cluster, while minimizing the number of connections between them. It can be computed using spectral and/or hierarchical clustering approaches, also called multi‐level schemes. Modularity metric measures the density of connections within a cluster compared to the total number of edges in the graph. WebHierarchical clustering is an unsupervised learning method for clustering data points. The algorithm builds clusters by measuring the dissimilarities between data. Unsupervised learning means that a model does not have to be trained, and we do not need a "target" variable. This method can be used on any data to visualize and interpret the ...
