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.
