How Affinity Propagation Clustering Works
Affinity Propagation exchanges messages between data points to identify exemplars — representative cluster centers — without needing K.

Key Metrics to Watch
Silhouette Score
Measures how similar a point is to its own cluster vs. other clusters. Ranges from −1 to +1; higher is better.
Calinski-Harabasz Index
Ratio of between-cluster to within-cluster variance. Higher values indicate denser, well-separated clusters.
Davies-Bouldin Index
Average similarity between each cluster and its most similar cluster. Lower is better.
Inertia (Within-Cluster SSE)
Sum of squared distances from each point to its assigned centroid. Lower indicates tighter clusters.
When to Use Affinity Propagation Clustering
Affinity Propagation Clustering belongs to the Probabilistic family of clustering algorithms. These methods model each cluster as a probability distribution, providing soft assignments and uncertainty estimates.
