WebMay 24, 2024 · K-Means Clustering. There are two main ways to do K-Means analysis — the basic way and the fancy way. Basic K-Means. In the basic way, we will do a simple kmeans() function, guess a number of clusters (5 is usually a good place to start), then effectively duct tape the cluster numbers to each row of data and call it a day. We will have to get ... WebOct 26, 2015 · K-means is a clustering algorithm that tries to partition a set of points into K sets (clusters) such that the points in each cluster tend to be near each other. It is unsupervised because the points have no external classification.
