Pros of Single-linkage:
- This approach can differentiate between non-elliptical shapes as long as the gap between the two clusters is not small.
Cons of Single-linkage:
- This approach cannot separate clusters properly if there is noise between clusters.
Pros of Complete-linkage:
- This approach gives well-separating clusters if there is some kind of noise present between clusters.
Cons of Complete-Linkage:
- This approach is biased towards globular clusters.
- It tends to break large clusters.
