Clustering and Unsupervised Methods in Machine Learning (Oct 2025) - NCI

This workshop is being run as part of a collaboration between QCIF and National Computational Infrastructure (NCI).

Unsupervised learning techniques, particularly clustering, are essential for discovering hidden patterns and structures in data. In this interactive workshop, participants will explore key unsupervised learning methods, including k-means clustering, hierarchical clustering, and density-based clustering. The session will also introduce dimensionality reduction techniques, including principal component analysis (PCA) and t-distributed stochastic neighbour embedding ( t-SNE ) for visualisation and feature extraction. Through interactive coding exercises in Python (Scikit-Learn, NumPy, Pandas, Matplotlib, Seaborn), attendees will apply clustering techniques to real-world datasets and learn how to evaluate the quality of clustering results. The workshop will also discuss applications of clustering in different domains, from customer segmentation to anomaly detection. By the end of the session, participants will have the practical skills to apply clustering and unsupervised learning methods effectively in data analysis. No prior machine learning…
