Challenge Problems
Push your limits with challenges.
Question 1
You have a dataset with several distinct natural clusters. Upon using K-Means, you find a Davies-Bouldin Index of 1.5 and a Silhouette Score of 0.3. What actions could you take to improve your clustering?
💡 Hint: Think about what these indices tell you about the current clustering quality.
Question 2
In an analysis, you're applying the Elbow Method and notice the elbow point is at K=4. However, you notice better cluster separation visually at K=6. How do you decide which K to use?
💡 Hint: Think of balancing visual observations with quantitative evaluations.
