Ai Hierarchical Clustering in AI & ML

Hierarchical Clustering builds a tree-like structure (dendrogram) of clusters without needing to specify K upfront. Unlike K-Means, you can cut the dendrogram at any level to get any number of clusters.

Agglomerative (bottom-up): Each point starts as its own cluster. Then repeatedly merge the two closest clusters until one remains. Most common approach.

Divisive (top-down): Start with all points in one cluster, repeatedly split until each point is its own cluster. Less common.

Linkage methods: Single linkage (distance = closest pair between clusters), Complete linkage (distance = farthest pair), Average linkage (distance = average of all pairs). Average and complete linkage generally produce better results.

Ai Hierarchical Clustering — Syntax

# Agglomerative Hierarchical Clustering:
# 1. Each point = its own cluster
# 2. Find two closest clusters
# 3. Merge them
# 4. Repeat until 1 cluster (or desired K)
#
# In sklearn:
# from sklearn.cluster import AgglomerativeClustering
# model = AgglomerativeClustering(n_clusters=3, linkage='average'
