WebGraph clustering is an important subject, and deals with clustering with graphs. The data of a clustering problem can be represented as a graph where each element to be clustered is represented as a node and the distance between two elements is modeled by a certain weight on the edge linking the nodes [1].Thus in graph clustering, elements within a … WebNov 15, 2024 · After cutting a tree produced by hierarchical clustering, a data point should belong to only one cluster. Perhaps you should be concerned about whether 6 clusters are not too many, but that depends on what you want to do with the clusters and how much separation you can reasonably expect. thanks for the reply and help!
