WebFeb 9, 2024 · So yes, you will need to run k-means with k=1...kmax, then plot the resulting SSQ and decide upon an "optimal" k. There exist advanced versions of k-means such as X-means that will start with k=2 and then increase it until a secondary criterion (AIC/BIC) no longer improves. The optimal number of clusters k is one that maximizes the average silhouette over a range of possible values for k. Optimal of 2 clusters. Q3. How do you calculate optimal K? A.
