Vincent's solution of using second degree differences seems more robust.

WebThe basic idea behind this method is that it plots the various values of cost with changing k. As the value of K increases, there will be fewer elements in the cluster. So average distortion will decrease. The lesser number of elements means closer to the centroid. So, the point where this distortion declines the most is the elbow point.

WebJul 18, 2024 · To determine the optimal number of clusters, we must select the k value in the "knee", then is at the point after which distortion / inertia begins to decrease linearly.
