SciPy - Clustering and Distance

What does the linkage function in scipy.cluster.hierarchy do in hierarchical clustering?

AIt calculates distances between clusters step-by-step to form a hierarchy.

BIt assigns data points to fixed clusters before clustering.

CIt visualizes the final clusters using a scatter plot.

DIt normalizes the data before clustering.

Step-by-Step Solution

Solution:

Step 1: Understand hierarchical clustering process
Hierarchical clustering builds clusters step-by-step by merging closest groups.
Step 2: Role of linkage function
The linkage function calculates distances between clusters at each step to decide which to merge next.
Final Answer:
It calculates distances between clusters step-by-step to form a hierarchy. -> Option A
Quick Check:
Linkage = stepwise cluster distance calculation [OK]

Quick Trick: Linkage = stepwise cluster distance calculation [OK]
