Bisecting k means c++

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). WebBisecting K-Means and Regular K-Means Performance Comparison ¶ This 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.
