What is a key advantage of using hierarchical clustering over K-means?
Correct Answer: Hierarchical clustering does not require the number of clusters to be predetermined.
- Step 1: Understand that clustering is a way to group similar data points together.
- Step 2: Know that K-means clustering requires you to decide how many groups (clusters) you want before starting.
- Step 3: Realize that hierarchical clustering does not need you to set the number of clusters in advance.
- Step 4: Recognize that this flexibility allows you to explore the data and find the best number of clusters based on the data itself.
- Step 5: Conclude that the key advantage of hierarchical clustering is its ability to adapt to the data without needing a fixed number of clusters.
