Bisecting k means algorithm

WebThis example shows differences between Regular K-Means algorithm and Bisecting K-Means. While K-Means clusterings are different when increasing n_clusters, Bisecting K-Means clustering builds on top of the previous ones. As a result, it tends to create clusters that have a more regular large-scale structure. WebOct 12, 2024 · Bisecting K-Means Algorithm is a modification of the K-Means algorithm.
