Q: Which evaluation metric is best for assessing clustering algorithms?
Solution: Silhouette Score is used to evaluate clustering algorithms by measuring how similar an object is to its own cluster compared to other clusters.
Steps: 5
Step 1: Understand what clustering is. Clustering is a way to group similar items together.
Step 2: Know that we need a way to measure how good our clusters are.
Step 3: Learn about the Silhouette Score. It helps us see how well each item fits in its cluster.
Step 4: The Silhouette Score ranges from -1 to 1. A score close to 1 means the item is well placed in its cluster.
Step 5: Compare the Silhouette Score of different clustering results to find the best one.
