Practical Guide to Cluster Analysis in R (book)

july 2018 by lena

Although there are several good books on unsupervised machine learning/clustering and related topics, we felt that many of them are either too high-level, theoretical or too advanced. Our goal was to write a practical guide to cluster analysis, elegant visualization and interpretation.

The main parts of the book include:

distance measures,

partitioning clustering,

hierarchical clustering,

cluster validation methods, as well as,

advanced clustering methods such as fuzzy clustering, density-based clustering and model-based clustering.

Independent component analysis (ICA) might offer an insightful alternative. ICA provides components that are not constrained to be orthogonal with each other; this means that for some purposes ICs might be more helpful than PCs.

Looking to answer the qualitative aspect of the OP's original question: What if I know I only want two principal components in order to visualize my data in 2-dimensions ? ICs can be rather helpful as ICA tries to minimize the mutual information among the projected dat...

Principal component analysis (PCA) is a mainstay of modern data analysis - a black box that

is widely used but poorly understood. The goal of this paper is to dispel the magic behind this

black box. This tutorial focuses on building a solid intuition for how and why principal component analysis works; furthermore, it crystallizes this knowledge by deriving from simple intuitions, the mathematics behind PCA. This tutorial does not shy away from explaining the ideas in formally, nor does it shy aw...
