Clustering Explained — k-Means, Hierarchical & DBSCAN Visually | Master AI & ML Ep 14

Clustering is where machine learning goes unsupervised — no labels, no correct answers, just data and the question: is there hidden structure here? In this episode we animate k-means from scratch, tackle the deceptively hard problem of choosing k, explore hierarchical clustering and DBSCAN, and confront the hardest question in all of clustering: how do you know if it worked?

In this episode:
→ The unsupervised shift — what changes when there's no target variable
→ Real use cases: customer segmentation, anomaly detection, document grouping, image compression
→ k-means step by step — animated convergence from random centroids to stable clusters
→ Choosing k — the elbow method and silhouette score explained
→ When k-means fails — elongated clusters and concentric rings
→ Hierarchical clustering — the dendrogram explained visually
→ DBSCAN — density-based clustering with built-in outlier detection
→ Evaluating clustering without ground truth — the hardest problem in unsupervised ML

This is Episode 14 of Master AI & Machine Learning — Module 3: Core ML Algorithms, Episode 4 of 6.
