SciPy - Clustering and Distance
Which linkage method in
scipy.cluster.hierarchy.linkage uses the minimum distance between points in clusters?Which linkage method in scipy.cluster.hierarchy.linkage uses the minimum distance between points in clusters?
easy📝 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Recall linkage methods and their distance criteria
Single linkage uses the minimum distance between points in two clusters.Step 2: Contrast with other methods
Complete uses maximum distance, average uses mean distance, ward minimizes variance.Final Answer:
single -> Option DQuick Check:
single linkage = minimum distance [OK]
Quick Trick: Single linkage = minimum distance between clusters [OK]
Common Mistakes:
- Mixing single with complete linkage
- Confusing average linkage with single
- Assuming ward uses minimum distance
