WebNov 3, 2016 · Bisecting k-means iteratively breaks down the cluster with the highest dissimilarity into smaller clusters. Since you are already producing 100+ clusters, it seems to me that maybe the 400k entry cluster has a very high similarity score. I'd try to visualize the clusters via stratified sampling and then t-SNE. It might be that the 400k entries ... WebThe algorithm starts from a single cluster that contains all points. Iteratively it finds divisible clusters on the bottom level and bisects each of them using k-means, until there are k …
