Bisecting k means c++
WebFeb 14, 2024 · The bisecting K-means algorithm is a simple development of the basic K-means algorithm that depends on a simple concept such as to acquire K clusters, split … WebBisecting 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.

The idea is iteratively splitting your cloud of points in 2 parts. In other words, you build a random binary tree where each splitting (a node with two children) corresponds to splitting the points of your cloud in 2. You begin with a cloud of points.
