WebIn early iterations, the cluster centers shift quite a lot. By the 14th iteration, they have settled down to the general area of their final location, and the last four iterations are minor adjustments. If the algorithm stops because the maximum number of iterations is reached, you may want to increase the maximum because the solution may ... WebMay 19, 2024 · Cluster 1 consists of observations with relatively high sepal lengths and petal sizes. Cluster 2 consists of observations with extremely low sepal lengths and petal sizes (and, incidentally, somewhat high sepal widths). Thus, going just a little further, we might say the clusters are distinguished by sepal shape and petal size.

The within-cluster sum of squares is a measure of the variability of the observations within each cluster. In general, a cluster that has a small sum of squares is more compact than a cluster that has a large sum of squares. Clusters that have higher values exhibit greater variability of the observations within the cluster.
