Bisecting k-means is a kind of hierarchical clustering using a divisive (or “top-down”) approach: all observations start in one cluster, and splits are performed recursively as one moves down the hierarchy. Bisecting K-means can often be much faster than regular K-means, but it will generally produce a different clustering. au ショップ方南町バイト
