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 Algorithm — Clustering in Machine Learning

WebJul 19, 2024 · Bisecting K-means is a clustering method; it is similar to the regular K-means but with some differences. In Bisecting K-means we initialize the centroids randomly or by using other methods; then we iteratively perform a regular K-means on the data with the number of clusters set to only two (bisecting the data). 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 the set of some points into two clusters, choose one of these clusters to split, etc., until K clusters have been produced. The k-means algorithm produces the input parameter, k, …
