Question 16
The elbow method involves plotting the number of clusters against the inertiaand identifying a point where the decrease in inertia slows down.
The elbow point represents the cluster count beyond which additional clustersdo not significantly improve the model fit.
The metric used in the elbow method is the silhouette score.
The elbow point is always the smallest number of clusters in the plot.
The elbow method may sometimes be inconclusive if no clear bend is visible inthe curve.
