What will you learn in Cluster Analysis and Unsupervised Machine Learning in Python Course

  • Master K-Means Clustering, its limitations, and extend it to soft (fuzzy) K-Means implementations.

  • Understand and implement Hierarchical Clustering methods, including dendrogram interpretation and linkage strategies (single, complete, Ward, UPGMA).

​​​​​​​​​​

  • Learn Gaussian Mixture Models (GMMs) and the Expectation-Maximization (EM) algorithm—when GMMs align with K-Means and how they address its weaknesses.

  • Apply Kernel Density Estimation (KDE) for density estimation and pattern discovery.

Program Overview

Module: Fundamentals & K-Means Clustering

⏳ ~2 hours

  • Topics: Introduction to unsupervised learning, the mechanics of standard and soft K-Means, drawbacks of cluster separation, initialization strategies.

  • Hands‑on: Implement K-Means manually and with libraries, and visualize clusters using Matplotlib/seaborn.

Module: Hierarchical Clustering & Linkage Methods

⏳ ~1.5 hours

  • Topics: Agglomerative clustering algorithms, linkage types, dendrogram construction, and cluster extraction.

  • Hands‑on: Use SciPy to cluster sample datasets and generate dendrogram visualizations.

Module: Gaussian Mixture Models & EM

⏳ ~2 hours

  • Topics: Understand EM convergence, covariance constraints, density estimation, and how GMM relates to K-Means.

  • Hands‑on: Code EM-based clustering from scratch; compare results against K-Means clustering.

Module: Kernel Density Estimation & Evaluations

⏳ ~1 hour

  • Topics: Introduce KDE for unsupervised density estimation and model evaluation techniques.

  • Hands‑on: Apply KDE using SciPy; compare estimated density plots to real data distributions.
