Overview

In this package, we implement standard PCA, kernel PCA, and pre-image reconstruction of Gaussian kernel PCA.

We also provide three demos:

  1. Two concentric spheres embedding;
  2. Face classification with PCA/kPCA;
  3. Active shape models with kPCA.

Standard PCA is not optimized for very high dimensional data. But our kernel PCA implementation is very efficient, and has been used in many research projects.

1.4.0.0

Fixed a fatal bug in pre-image reconstruction.

1.3.0.0

addpath('../code') in demo2

1.2.0.0

We replaces all demos, and the data used for the demo. We also updated the document to provide better illustration and better experiments. Now the code generates exactly the same results as shown in the paper.

1.1.0.0

The efficiency is optimized.

1.0.0.0
