How does the Elbow Method determine the optimal number of clusters, and what are its limitations?
- By evaluating the model's accuracy
- By finding the point of maximum curvature on a plot of variance vs. clusters
- By maximizing the cluster distances
- By minimizing the inter-cluster distances
The Elbow Method determines the optimal number of clusters by finding the "elbow" point on a plot of variance vs. clusters. Limitations include ambiguity in identifying the exact "elbow" and sensitivity to initialization.
