WebThere are a variety of clustering algorithms; one of them is the agglomerative hierarchical clustering. This clustering method helps us to represent graphically the results through a dendogram. The dendogram has a tree structure that consists of the root and the leaves; the root is the cluster that has all the observations, and the leaves are ... WebIn this paper, we present a scalable, agglomerative method for hierarchical clustering that does not sacrifice quality and scales to billions of data points. We perform a detailed theoretical analysis, showing that under mild separability conditions our algorithm can not only recover the optimal flat partition but also provide a two-approximation to non …
