Principal Component Analysis (PCA) - A.B. Dufour - course2.pdf

26 days ago by lena

Interesting tutorial, with 3D plots that explain effects of scaling/centering. Uses dudi.pca r code: "dudi.pca deals with the variables and/or the individuals whereas princomp

and prcomp deal with the individuals only. "

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...

A Tutorial on Principal Component Analysis - Jonathon Shlens - 2005

6 weeks ago by lena

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...
