Learn unsupervised machine learning using K-Means and Hierarchical Clustering to identify patterns in unlabeled data

intermediate Published 30 Apr 2026
Action Steps
  1. Apply K-Means clustering to a sample dataset using scikit-learn in Python to identify cluster assignments
  2. Run Hierarchical Clustering on a dataset using SciPy to visualize dendrograms and understand cluster relationships
  3. Configure clustering hyperparameters, such as the number of clusters (K) and distance metrics, to optimize model performance
  4. Test the robustness of clustering models using metrics like silhouette scores and Calinski-Harabinski index
  5. Compare the results of K-Means and Hierarchical Clustering on the same dataset to determine the most suitable approach
