Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a dataset with varying densities, how would you select an appropriate clustering algorithm, and why?

💡 Hint: Consider how different algorithms react to challenges in data structure.

Challenge 2 Hard

You have a dendrogram from hierarchical clustering showing multiple merges. Discuss how you would decide where to make the cut for clusters.

💡 Hint: Look for distance thresholds in the dendrogram that indicate promising cluster arrangements.
