WebApr 12, 2024 · K-means clustering is an unsupervised learning algorithm that groups data based on each point euclidean distance to a central point called centroid. The centroids are defined by the means of all points that are in the same cluster. The algorithm first chooses random points as centroids and then iterates adjusting them until full convergence. WebThe Elbow Method. A method of interpreting a scree plot is to use the elbow rule. This method is about looking for the “elbow” shape on the curve and retaining all components before the point where the curve flattens out. For the demonstration, we used the built-in mtcars data and the measure of explained variance percentage.
