4 Clustering and association algorithm
-
M. Ashwin
Abstract
This chapter provides an extensive examination of clustering and association algorithms, offering a comprehensive understanding of these essential unsupervised learning techniques in the field of machine learning. The chapter commences with an introductory section that underscores the significance of unsupervised learning, and presents a detailed overview of clustering and association algorithms. The various clustering algorithms covered in the following sections are k-means, hierarchical clustering, densitybased clustering (like DBSCAN), and Gaussian mixture models. Additionally, the chapter explores evaluation metrics for clustering, including both internal and external evaluation metrics, and offers advise on how to properly interpret the evaluation results. The chapter also examines dimensionality reduction methods, particularly principal component analysis and t-SNE, and clarifies how to use them in clustering scenarios. The Apriori algorithm, frequent itemset mining, association rule development, and methods for judging rule interestingness are all covered in the section on association rule learning. Along with explaining their individual uses, the chapter also goes into advanced clustering methods like density-based spatial clustering, mean-shift clustering, spectral clustering, and affinity propagation. The chapter also discusses association rule mining, ensemble clustering, and time series clustering in huge datasets. The chapter concludes with an overview of the core ideas and developments in unsupervised learning, along with a list of the field’s present research roadblocks and potential future paths.
