WebJul 18, 2024 · Figure 1: Ungeneralized k-means example. To cluster naturally imbalanced clusters like the ones shown in Figure 1, you can adapt (generalize) k-means. In Figure 2, the lines show the cluster boundaries after generalizing k-means as: Left plot: No generalization, resulting in a non-intuitive cluster boundary. Center plot: Allow different … WebAug 14, 2024 · It means we are given K=3.We will solve this numerical on k-means clustering using the approach discussed below. First, we will randomly choose 3 centroids from the given data. Let us consider A2 (2,6), A7 (5,10), and A15 (6,11) as the centroids of the initial clusters. Hence, we will consider that.
